Products Detail

The MCP1603/B/L is a high-efficiency, fully-integrated 500mA synchronous buck regulator with 2.7V to 5.5V input voltage range, making it suitable for 1-cell Li-Ion or 2-cell/3-cell NiMH/NiCd batteries. It operates in 2.0MHz fixed frequency PWM mode at heavy loads for low noise and small solution size, and automatically transitions to PFM mode at light loads to minimize quiescent current. The family offers adjustable (0.8V to 4.5V) or fixed output voltage options (1.2V, 1.5V, 1.8V, 2.5V, 3.3V for MCP1603/L; 1.8V, 3.3V for MCP1603B). Features include internally compensation, UVLO, overtemperature protection, and space-saving packages.
