General Description

The AS1302 is a 30mA inductorless boost converter using a double H-bridge charge-pump topology with two external flying capacitors.

The AS1302 charge pump

Key Features

1:2 and 2:3 operation modes as well as a 1:1 operation mode where the input is directly connected to the output. The AS1302 runs on a 1.2MHz fixed frequency and is utilized with a low noise regulation scheme to allow usage together with sensitive RF circuitry from the same battery supply. Additionally to increase efficiency the AS1302 switches to 49kHz at light loads. Designed to reside in portable and space limited equipment the 1.2MHz charge pump converts a 2.9V to 5.15V input to regulated 5V.
