The AS1301 is a 50mA inductorless boost converter using a double H-bridge charge-pump topology with two small (≤220nF) 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 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 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.
