Product Summary
The AS1301EHT-ADJ is a 50mA inductorless boost converter using a double H-bridge charge-pump topology with two external flying capacitors. The AS1301EHT-ADJ 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. The AS1301EHT-ADJ is available in TDFN (3x3x0.8mm) 10-pin and WL-CSP 8-bumps packages. The AS1301EHT-ADJ is ideal for dual/triple AA cells or single Li-Ion battery cell to 5V conversion, mobile phones, portable instruments, microprocessor based systems, remote data-acquisition systems, inductorless DC-DC conversion.
