Microchip Technology, Inc. 750kHz 500mA Synchronous PFM/PWM Buck Regulator w/Frequency Synchronization en010706

Description
The MCP1601 is a synchronous Buck (step-down) switching regulator that can continuously supply 500mA of load current. This DC/DC converter can provide output voltages of 0.9V to Vin with an operating efficiency that can exceed 92%. Although ideally suited for a single Li-Ion, or 2 to 3 cell NiCd, NiMH, or alkaline battery operation, the input range of 2.7V to 5.5V is also useful for converting bus voltages to standard system requirements. Additional Features 3 operating modes (PWM, PFM, LDO) with automatic switching between modes Shutdown mode to minimize current drain during stand-bye conditions Oscillator Synchronization to 1.0MHz PWM mode Integrated Buck and Synchronous switches Complete ceramic capacitor solution Integrated UVLO, Soft-start, and Over temperature protection Short circuit protection -40°C to +85°C operation
