AS1301
5V/50mA Low Noise Inductorless Boost Converter

Datasheet
1 General Description
The AS1301 is a 50mA inductorless boost converter using a double
H-bridge charge-pump topology with two external flying capacitors.
The AS1301 runs on a 1MHz fixed frequency and is utilized with a
low noise regulation scheme to allow usage together with sensitive
RF circuitry fromthe same battery supply.
Designed to reside in portable and space limted equipment the
1MHz charge pump converts a 2.7 to 5.25V input to regulated 5V
output with 5% accuracy.
The shutdown function reduces the supply current to <5μA and
disconnects the load fromthe output. The integrated soft-start
circuitry prevents current spikes being drawn fromthe battery during
start-up.
The AS1301 is available in TDFN (3x3x0.8mm 10-pin and WL-CSP
8-bumps packages.
