Analog Devices ADP2503/ADP2504 Datasheet
The ADP2503/ADP2504 converters provide step‑up/step‑down regulation from 2.3 V to 5.5 V input and fixed output options from 2.8 V to 5.0 V. They feature a 1 mm height profile, 10‑lead LFCSP package, seamless mode transition, internal compensation, soft‑start, and a SYNC pin that supports power‑save, forced‑frequency, or external‑clock synchronization.
Typical applications include wireless handsets, digital cameras, portable audio players, miniature hard‑disk power supplies and USB‑powered devices. The device includes over‑temperature, short‑circuit, and undervoltage lockout protection, and can operate in both boost and buck‑boost configurations with a quiescent current as low as 38 pA.
