Fast load response is achieved by controlling the output voltage using a comparator without relying on the switching frequency. When VOUT drops due to a rapid load change, the system quickly restores VOUT by extending the tON time interval. Thus, it serves to improve the regulator’s transient response. Activating the light load mode further increases efficiency by using Simple Light Load Mode (SLLM) control. H3RegTM Control (Normal operation) (VOUT drops due to a rapid load change) FB VOUT/VIN Circuit Transient Circuit Driver HG SW LG VIN VOUT FB REF HG LG HG output on-time is determined by the formula (1). When HG is off, LG is on until the output voltage becomes FB= REF. When FB falls to a reference voltage (REF), the drop is detected, activating the H3RegTM control system FB REF HG Io LG tON+α When VOUT drops due to a rapid load change, and the voltage remains below the output setting following the programmed tON time, the system quickly restores VOUT by extending the tON time, thus improving the transient response. Once VOUT is restored, the controller continues normal operation. tON= VOUT VIN x 1 f [sec]・・・(1) Comparator for Output voltage control Internal Reference Voltage REF

When the FB input is lower than REF voltage again, HG will be enabled once again. FB REF HG LG LOAD COUT *Attention: To affect the rapid transient response, the H3RegTM control monitors the current from the output capacitor to the load using the ESR of the output capacitor Do not use ceramic capacitors on COUT side of power supply. Ceramic bypass capacitors can be used near the individual loads if desired.

Current control takes effect at startup enabling a moderate output voltage “ramping.” Soft start timing and incoming current are calculated with the following: formulas (2) and (3) below. tSS= 0.75(Typ) x CSS 2µA(Typ) [sec] ・・・(2) IIN = CO x VOUT tSS [A] ・・・(3) x VOUT VIN (CSS: Soft start capacitor C O: Output capacitor) FB SCP EN/UVLO tSCP REF x 0.56 Short circuit protection is enabled when FB falls to or below REF X 0.56. Once the programmed time period has elapsed, the output is latched off to prevent destruction of the circuit. Output voltage can be restored either by cycling the EN pin or disabling UVLO. Short circuit protection time is programmed at 2.5msec (Typ). tMAX tON tON HG LG IL ILIMIT During normal operation, if FB is less than REF, HG is high during the time tON, but when the coil current exceeds the ILIMIT threshold, HG is set to off.

Inductor (L) Selection *Passing a current larger than inductor’s rated current will cause magnetic saturation in the inductor and decrease system efficiency. When selecting the inductor, be sure to allow enough margin to assure that peak currents do not exceed the inductor rated current value. *To minimize possible inductor damage and maximize efficiency, choose a inductor with a low (DCR, ACR) resistance. 2. Output Capacitor (Co) Selection Please give due consideration to the conditions in formula (7) below for the output capacitor, bearing in mind that the output start-up time must be established within the soft start timeframe. Capacitors used as bypass capacitors are connected to the load side affect the overall output capacitance ( CEXT, figure above). Please set the soft start time or over-current detection value, regarding these capacities. If an inappropriate capacitor is used, OCP may be detected during activation and may cause startup malfunctions. 3.

ΔIL= (VIN - VOUT) x VOUT L x VIN x f [A]・・・(4) PGND PGND ΔIL VIN IL L CO VOUT Output ripple current Generally, lower inductance values offer faster response times but also result in increased output ripple and lower efficiency. 0.47μH to 2.2μH are a recommended range of values. The peak current rating of the coil is approximated by formula (5). Please select an inductor equal to or higher than this value. ILPEAK= IOUTMAX + (VIN-VOUT) x VOUT 2 x L x VIN x f [A]・・・(5) The inductor value is a major influence on the output ripple current. As formula (4) below indicates, the greater the inductor or the switching frequency, the lower the ripple current.

The rating of the capacitor is set with sufficient margin given the output voltage. ΔIL: Output ripple current ESR: Equivalent series resistance, ESL: Equivalent series inductance Input capacitor IRMS= IOUT x VOUT (VIN -VOUT) VIN [A]・・・(8) Where VIN = 2 x VOUT, IRMS= IOUT PGND PGND L CO VOUT Cin The input capacitor selected must have low enough ESR to fully support high output ripple so as to prevent extreme over current conditions. The formula for ripple current IRMS is given in (8) below. VIN

Reverse Connection of Power Supply Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power s upply, such as mounting an external diode between the power supply and the IC ’s power supply pins. 2. Power Supply Lines Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog block. Furthermore, connect a capacitor to ground at all power supply pins . Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. 3. Ground Voltage Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition. 4. Ground Wiring Pattern When using both small-signal and large-current ground traces, the two ground trace s should be routed separately but connected to a single ground at the reference point of the application board to avoid fluctuations in the small -signal ground caused by large currents. Also ensure that the ground traces of external components do not cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance. 5. Thermal Consideration Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. The absolute maximum rating of the Pd stated in this specification is when the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating. 6. Recommended Operating Conditions These conditions represent a range within which the expected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. 7. Inrush Current When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of connections. 8. Operation Under Strong Electromagnetic Field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 9. Testing on Application Boards When testing the IC on an application board, connecting a capacitor directly to a low -impedance output pin may subject the IC to stress. Always discharge capacitors co mpletely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 10. Inter-pin Short and Mounting Errors Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in damaging the IC. Avoid nearby pins being shorte d to each other especially to ground , power supply and output pin . Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few.

Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment, OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you intend to use our Products in devices requiring extremely high reliability ( such as medical equipment (Note 1), transport equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life , bodily injury or serious damage to property ( “Specific Applications”), please consult with the ROHM sales representative in advance. Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any damages, expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for Specific Applications. (Note1) Medical Equipment Classification of the Specific Applications JAPAN USA EU CHINA CLASSⅢ CLASSⅢ CLASSⅡb CLASSⅢ CLASSⅣ CLASSⅢ 2. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsi bilities, adequate safety measures including but not limited to fail -safe design against the physical injury, damage to any property, which a failure or malfunction of our Products may cause. The following are examples of safety measures: [a] Installation of protection circuits or other protective devices to improve system safety [b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure 3. Our Products are designed and manufactured for use under standard conditions and not under any special or extraordinary environments or conditions, as exemplified below . Accordingly, ROHM shall not be in any way responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any special or extraordinary environments or conditions . If you intend to use our Products under any special or extraordinary environments or conditions (as exemplified below), your independent v erification and confirmation of product performance, reliability, etc, prior to use, must be necessary: [a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents [b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust [c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2 [d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves [e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items [f] Sealing or coating our Products with resin or other coating materials [g] Use of our Products without cleaning residue of flux (even if you use no -clean type fluxes, cleanin g residue of flux is recommended); or Washing our Products by using water or water -soluble cleaning agents for cleaning residue after soldering [h] Use of the Products in places subject to dew condensation 4. The Products are not subject to radiation-proof design. 5. Please verify and confirm characteristics of the final or mounted products in using the Products. 6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied, confirmation of pe rformance characteristics after on -board mounting is strongly recommended. Avoid applying power exceeding normal rated power; exceeding the power rating under steady -state loading condition may negatively affect product performance and reliability. 7. De-rate Power Dissipation d epending on ambient temperature. When used in sealed area, confirm that it is the use in the range that does not exceed the maximum junction temperature. 8. Confirm that operation temperature is within the specified range described in the product specification. 9. ROHM shall not be in any way responsible or liable for failure induced under devian t condition from what is defined in this document. Precaution for Mounting / Circuit board design 1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product performance and reliability. 2. In principle, the reflow soldering method must be used on a surface -mount products, the flow soldering method must be used on a through hole mount products. If the flow soldering method is preferred on a surface -mount products , please consult with the ROHM representative in advance. For details, please refer to ROHM Mounting specification
