Product Information
Product Overview
The MCP1651R-E/MS is a 750kHz gated Oscillator Boost Controller for high-power, portable applications, it can deliver 5W of power to the load while consuming only 120µA of quiescent current at no load. The MCP1651 can operate over a wide input voltage range (2.0 to 5.5V) to accommodate multiple primary-cell and single-cell Li-Ion battery-powered applications, in addition to 2.8, 3.3 and 5.0V regulated input voltages. An internal gated oscillator makes the MCP1651 ideal for space-limited designs. High switching frequency minimizes the size of the external inductor and capacitor, saving board space and cost. The internal oscillator operates at two different duty cycles depending on the level of the input voltage. By changing duty cycle in this fashion, the peak input current is reduced at high input voltages, reducing output ripple voltage and electrical stress on power train components.
