Offline Inductor-Less Regulator For Low Power Applications MP103 Rev. 1.01 www.MonolithicPower.com 1 1/23/2014 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2014 MPS. All Rights Reserved. The Future of Analog IC Technology

DESCRIPTION

The MP103 provides an easy and low cost ACDC solution for less than 1W applications. It is an off-line linear regulator that delivers good efficiency while generating little EMI noise. It provides an easy solution to step down the AC line voltage to a regulated DC voltage. This off- line linear regulator replaces the conventional switching regulator, not needing a transformer or an inductor. Due to its simplicity, it offers an overall low BOM cost. MP103 delivers nearly two times the output power than the MP100 or MP100L by charging its VB capacitor with an external bipolar transistor. MP103 maximizes efficiency by minimizing the voltage drop between VB and VOUT, while only charging VB when VIN is less than approximately 32V. The MP103 enables the overall system to meet standby power requirements. MP103 offers rich protections, such as Thermal Shutdown (TSD), Over Temperature Protection (OTP), VB Over Voltage Protection (OVP), VB Short to GND Protection, Over Load Protection (OLP), Short Circuit Protection (SCP), MP103 is available in the SOIC8E package.

The value of the NTC resistor becomes lower when the ambient temperature rises. With the fixed internal current 80uA flowing through the resistors, the voltage of RT pin becomes lower at high temperature. When VRT is lower than VRTTHL （typically 0.8V ）, then internal OTP circuit will be triggered and the BJT driver and LDO will be shut down immediately. When VRT is higher than VRTTHL plus VRTTH_HYS, then MP103 will restart. Thermal Shutdown Protection Accurate temperature protection prevents the chip from operating at exceedingly high temperatures. When the silicon die temperature exceeds 160 oC, the whole chip shuts down. When the temperature falls below its lower threshold of 140 oC, the chip is enabled again.

Unauthorized Photocopy and Duplication Prohibited. © 2014 MPS. All Rights Reserved. EMI To meet the relevant conducted emissions standard, slowly rise and fall the driver current is adopted to turn on and turn off the external BJT. Using this control method, a smaller X cap connected between the input ports will pass EMI with enough margins. Besides, a capacitor connected between DR and VB will further slow down the switching process of external BJT for better EMI performance. The larger value this capacitor used, the slower switching process and better EMI performance will be got, however, the more power losses will be introduced by this capacitor and the longer startup process will be, so it is a compromise to select the value of the capacitor connected. Generally, with a 100nF X cap connected to pass EMI, a 2.2uF ceramic capacitor for 12V output and 4.7uF ceramic capacitor for 5V output is a good candidate to get good compromise. Surge From its working principle, MP103 is working just when VIN falls into its charging window, so when surges happen at this moment, then a lot of energy will be absorbed by BJT and MP103 due to the slow turn off process. To protect them from damage, a fast turn off threshold (typically it is 71V) of VIN is set specially to shut down driver current quickly. Since there is no bulk capacitor to absorb AC line transients, MOV should be used to protect the IC to survive the surge test. Besides the value of fuse resistor will also affect the surge result, the larger value used, the better to facilitate to pass the surge test, but the more power consumption will be caused, in the meanwhile, the larger value of fuse resistor used, the easier to trigger its fast turn off threshold, so 10~20 Ω fuse resistor is recommended in real application. To pass 1kV surge test, 750V external BJT is recommended considering some margin, MP103 can pass 1kV surge test with an appropriate MOV such as TVR10431 connected between the line input ports. Besides, the thermal pad must be connected to the GND for better surge performance. PCB Layout Guide PCB layout is very important to achieve good regulation, ripple rejection, transient response and thermal performance. It is highly recommended to duplicate EVB layout for optimum performance. If change is necessary, please follow these guidelines and take figure 6 for reference. 1) Keep the trace from positive output rectifier to VIN as short and wide as possible. 2) Minimize the loop area formed by positive output of rectifier, emitter of external BJT and GND. 3) Minimize the loop area formed by VIN, collector of BJT, emitter of BJT. 4) Ensure all feedback connections are short and direct. Place the feedback resistors and compensation components as close to the chip as possible. 5) Place the NTC resistor as close to external BJT as possible for temperature detection and effective protection. 6) Output capacitor should be put close to the output terminal. 7) Connect the exposed pad with GND to a large copper area to improve thermal performance and long-term reliability.
