ANALOG DEVICES ADP5041handbookRev 0
The ADP5041 combines a high‑performance 1.2 A buck regulator and two 300 mA low‑dropout regulators in a compact 20‑lead LFCSP package. It offers a wide input range of 2.3 V‑5.5 V, up to 96 % peak efficiency, and includes supervisory, watchdog and manual reset functions for microprocessor‑based systems.
The device provides selectable buck modes (forced PWM or power‑save PWM/PSM), programmable output voltages via external resistor dividers, and extensive protection features such as over‑current, thermal shutdown, and undervoltage lockout. Detailed pin descriptions, recommended external components, and factory‑programmable options are included.
