FAN5665 Datasheet Adaptive Charge Pump 5V Boost

Manufacturer: Fairchild (now onsemi)

Overview: FAN5665 — High-Efficiency, Adaptive Charge Pump 5V Boost February 2008 www.datasheet4u.

Datasheet Details

The FAN5665 is a 5V switched capacitor step-up DC/DC converter with an input voltage range from 2.9V to 5.5V.

Switch reconfiguration and fractional switching techniques are utilized to achieve high efficiency over the entire input voltage range.

The FAN5665 includes built-in under-voltage lockout, short circuit, and thermal protection circuitry.

5V Fixed Output Voltage 30mA Maximum Output Current Built-in Charge Pump with Three Modes of Operation: 1×, 1.5×, and 2× Minimum External Components Flying Capacitors Only 0.22µF Low-noise, Constant-frequency Operation (1.2MHz) at Heavy Loads High-efficiency, Low-frequency Operation at Light Loads Low Quiescent Current Up to 92% Efficiency 2.9V to 5.5V Input Voltage Range Soft-start for Limiting Inrush Curr.
