FAN5602 - Fairchild Semiconductor

FAN5602 Universal (Step-Up/Step-Down) Charge Pump Regulated DC/DC Converter

The FAN5602 is a universal switched capacitor DC/DC converter capable of step-up or step-down operation. Due to its unique adaptive fractional switching topology, the device achieves high efficiency over a wider input/output voltage range than any of its predecessors. The FAN5602 utilizes resistance modulated loop control, which produces lower switching noise.
