The ADP5022 integrates two buck converters (Buck1 and Buck2) and a low‑dropout regulator (LDO1) in a single PMU. It operates from a 2.4 V to 5.5 V input range and provides up to 600 mA from each buck converter and 150 mA from the LDO. The device supports PWM and PSM modes and includes UVLO, ESD protection, and thermal management features.
Typical applications include USB power supplies, ASICs, FPGAs and RF circuits. The package is a 2 mm × 2 mm WLCSP with a 16‑pin array. Electrical characteristics such as PSRR, quiescent current and temperature range are detailed in the datasheet.
| Input voltage range | 2.4 V to 5.5 V |
|---|---|
