The MCP1602 is a high efficient, fully integrated 500 mA synchronous buck regulator with a power-good monitor. It is ideally suited for applications powered from 1-cell Li-Ion or 2-cell/3-cell NiMH/NiCd batteries.
The MCP1602 is a high‑efficiency, fully integrated 500 mA synchronous buck regulator featuring a 2 MHz fixed‑frequency PWM mode, automatic PWM‑to‑PFM transition, and a power‑good output monitor. It operates from a 2.7 V to 5.5 V input range and offers both adjustable (0.8 V‑4.5 V) and fixed output options (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V).
Typical applications include cellular phones, portable computers, USB‑powered devices, digital cameras and other battery‑powered equipment. The device includes UVLO, over‑temperature and over‑current protection, and is available in 8‑lead MSOP or 8‑lead 3×3 DFN packages.
