APW9103
Active
3A, 18V, 600kHz Synchronous Step-Down Converter
Features
- N-CH MOSFET (38mΩ) for Low Side
General Description
The APW9103 is a high efficiency synchronous buck converter with integrated 70mΩ/38mΩ of upper/lower power MOSFET and offers 3A continuous current capability. The APW9103 uses a peak current mode control scheme to regulate the output voltage. The internal switching frequency is set at 600kHz. And EN/SYNC supports external clock synchronization. The APW9103 is also equipped with Power-on-reset, soft start, and whole protections (over-temperature, overvoltage, under-voltage, over-current) into a single package. The APW9103 is offered in a TSOT23-8 package allowing small size while having an excellent thermal capability for power dissipation.
