Datasheet AS1301 5V/50mA Low Noise Inductorless Boost Converter 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 from the same battery supply. Designed to reside in portable and space limited equipment the 1MHz charge pump converts a to 5.25V input to regulated 5V output with 5% accuracy. The shutdown function reduces the supply current to <5µA and disconnects the load from the output. The integrated soft-start circuitry prevents current spikes being drawn from the battery during start-up. The AS1301 is available in TDFN 3x3x0.8mm 10-pin and WL-CSP 8-bumps packages. 2 Key Features ! Up to 92% Efficiency ! to 5.25V Input Voltage ! Regulated 5V Output !
