Description

AP3603 is a dual output boost controller IC. The output voltage is set with an external resistor in the range up to 60V. The input voltage range is 6.4V to 20V, making it possible to configure a high-power boost power supply from battery devices.
The application of AP3603 supports dual output of 200W rated power × 2 channels and dual phase output of 400W rated power combining 1 channel and 2 channels output.
The driving frequency of AP3603 is set in the range of 40kHz to 500kHz by an external resistor. Equipped with output overvoltage protection and input overcurrent protection functions, it constitutes a space-saving, high-power step-up power supply.
AP3603 is offered in a 20-pin HTSSOP package.

Key Features

  • High power boost power supply
    Rated power 200W × 2 channels of dual output, or combined output of channels, rated power 400W can be output.

Applications

  •                                 Supports either 200W×2 channels dual outputs or 400W×1 channel dual phase single output.
