The ADP2102 is a synchronous step-down DC-to-DC converter with features such as low duty cycle, maximum 600 mA load current, 95% efficiency, etc.
The ADP2102 is a low‑duty‑cycle, 600 mA synchronous step‑down DC‑DC converter that operates from 2.7 V to 5.5 V input and delivers up to 95 % efficiency. It offers fixed output options from 0.8 V to 1.875 V and an adjustable version up to 3.3 V, with only three external ceramic components required.
The device is supplied in an 8‑lead, 3 mm × 3 mm LFCSP package and includes features such as internal synchronous rectification, soft‑start, power‑save mode (PSM), undervoltage lockout, current‑limit protection and thermal shutdown. Typical applications include USB‑powered devices, WLAN gateways, processor core power, digital cameras, PDAs and portable media players.
