All rights reserved. www.rohm.com TSZ22111･15･001 22.Jan.2024 Rev.005 Thermal design should ensure operation within the following conditions. Note that the temperatures listed are the al lowed temperature limits and thermal design should allow sufficient margin beyond these limits. 1. Ambient temperature Ta can be no higher than 85℃. 2. Chip junction temperature (Tj) can be no higher than 150℃. Chip junction temperature can be determined as follows: Calculation based on ambient temperature (Ta) Tj=Ta+θj-a×P ＜Reference values＞ θj-a：HTSOP-J8 153.2℃/W 113.6℃/W 59.2℃/W 33.3℃/W 1-layer substrate (copper foil density 0mm×0mm) 2-layer substrate (copper foil density 15mm×15mm) 2-layer substrate (copper foil density 70mm×70mm) 4-layer substrate (copper foil density 70mm×70mm) Substrate size: 70mm×70mm×1.6mm (substrate with thermal via) Most of the heat loss that occurs in the BDxxIC0WEFJ BDxxIC0JEFJ BDxxIC0WHFV series is generated from the output Pch FET. Power loss is determined by the total V CC-VO voltage and output current. Be sure to confirm the system input and output voltage as well as the output current conditions in relation to the heat dissipation characteristics of the VCC and VO in the design. Bearing in mind that heat dissipation may vary substantially depending on the substrate employed (due to the power package incorporated in the BDxxIC0W series )make certain to factor conditions such as substrate size into the thermal design. Power consumption [W] = Input voltage (VCC) - Output voltage (VO) ×IO(Ave) Example) When VCC=3.3V, VO=2.5V, IO(Ave) = 0.1A Power consumption [W] = 3.3V - 2.5V ×0.1A =0.08[W]

Input-to-Output Capacitor It is recommended that a capacitor (over 1uF) is placed near pins between the input pin and GND as well as the output pin and GND. A capacitor, between input pin and GND, is valid when the power supply impedance is high or trace is long. Also, as for the capacitor between the output pin and GND, the greater the capacitance, the more sustainable the line regulation will be and the capacitor will make improvement s of characteristics depending on the load. However, please check the actual functionality of this part by mounting it on a board for the actual application. Ceramic capacitors usually have different, thermal and equivalent series resistance characteristics, and moreover capacitance decreases gradually in use. For additional details, please check with the manufacturer, and select the best ceramic capacitor for your application.
Equivalent Series Resistance ESR (Output Capacitor) To prevent oscillations, please attach a capacitor between VO and GND. Capacitor s usually have ESR (Equivalent Series Resistance). Operation will be stable in the ESR-IO range shown to the right. This reference data condition is 1.0uF Ceramic capacitor and resistor are connected to output in series. Ceramic, tantalum and electrolytic Capacitors have different ESR values , so please ensure that you are using a capacitor that operates in the stable operating region shown on the right. Finally, please evaluate in the actual application.

Board Layout PCB layout considerations: ・Input capacitor CIN connected to VCC (Vin) should be placed as close to VCC(VIN) pin as possible. Output capacitor C OUT also should be placed as close to IC pin as possible. In case the part is connected to inner layer GND plane, please use several through holes. ・FB pin has comparatively high impedance and can be affected by noise, so stray capacitance should be as small as possible. Please take care of this during layout. ・Please make GND pattern wide enough to handle thermal dissipation. ・For output voltage setting Output voltage can be set by FB pin voltage (0.800V typ.) and external resistance R1, R2.

Operational Notes (1) Absolute maximum ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down the device, thus making it impossible to identify the damage mode, such as a short circuit or an open circuit. If there is any possibility of exposure over the rated values, please consider adding circuit protection devices such as fuses. (2) Connecting the power supply connector backward Connecting of the power supply in reverse polarity can damage the IC. Take precautions when connecting the power supply lines. An external direction diode can be added. (3) Power supply lines Design the PCB layout pattern to provide low impedance GND and supply lines. To obtain a low noise ground and supply line, separate the ground section and supply lines of the digital and analog blocks. Furthermore, for all power supply terminals to ICs, connect a capacitor between the power supply and GND terminal. When using electrolytic capacitors in a circuit, note that capacitance values are reduced at low temperatures and over time. (4) GND voltage The potential of the GND pin must be minimum potential under all operating conditions. (5) Thermal design Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions. (6) Off-leakage at high temperature. Off-leakage at high temperature may increase because of manufacturing variations. Design should consider the typical & worst cases shown below. (7) Inter-pin shorts and mounting errors Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any connection error or if pins are shorted together. (8) Actions in strong electromagnetic field Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to malfunction. (9) ASO When using the IC, set the output transistor so that it does not exceed absolute maximum ratings or ASO. (10) Thermal shutdown circuit The IC incorporates a built -in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit (TSD circuit) is designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or guarantee its operation. Do not continue to use the IC after operating this circuit or use the IC in an environment where the operation of this circui t is assumed. TSD ON Temperature[℃] (typ.)

All rights reserved. www.rohm.com TSZ22111･15･001 22.Jan.2024 Rev.005 (11)Testing on application boards When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress. Always discharge capacitors after each process or step. Always turn the IC ’s power supply off before connecting it to or removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps as an antistatic measure. Use similar precaution when transporting or storing the IC. (12) Regarding input pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of these P layers with the N layers of other elements, creating a parasitic diode or transistor. For example, the relation between each potential is as follows: When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes can occur inevitable in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic diodes operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be used. (13) Ground Wiring Pattern. When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns, placing a single ground point at the ground potential of application so that the pattern wiring resistance and voltage variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to change the GND wiring pattern of any external components, either.

Please be sure to implement, at your own responsibilities, 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 verification 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 (Exclude cases where no-clean type fluxes is used. However, recommend sufficiently about the residue.) ; 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 performance 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 depending 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 deviant 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. I f 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
