High Power Dual Output Step-Up DC-DC Controller
1. General Description 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 output. PWM switching frequency is set from 40kHz to 500kHz by an external resistor. As the protective functions, it has output over voltage protection and over current protection. The AP3603 is housed in a space-saving 20-pin HTSSOP package.
