AP3603 - AKM

AP3603 High Power Dual Output Step-Up DC-DC Controller

The AP3603 is a dual output step-up DC-DC controller. The output voltage can be set up to 60V by an external feedback resistor. A wide input range of 6.4V to 20V is available, which is possible to realize a high power boost source from the battery or the other power sources. The AP3603 supports either 200W×2ch dual outputs or 400W×1ch dual phase single outpu.
