AI
The MCP1652 is a 750 kHz gated oscillator boost controller packaged in an 8 or 10-pin MSOP package. Developed for high-power, portable applications, the gated oscillator controller can deliver 5 watts of power to the load while consuming only 120 µA of quiescent current at no load. The MCP1652 can operate over a wide input voltage range (2.0V to 5.5V) to accommodate multiple primary-cell and singlecell Li-Ion battery-powered applications, in addition to 2.8V, 3.3V and 5.0V regulated input voltages.
