Product Overview
The MCP1650R-E/MS is a 750kHz gated oscillator Boost Controller developed for high-power applications, the gated oscillator controller can deliver 5 watts of power to the load while consuming only 120µA of quiescent current at no load. It can operate over a wide input voltage range (2 to 5.5V) to accommodate multiple primary-cell and singlecell Li-Ion battery-powered applications, in addition to 2.8, 3.3 and 5V regulated input voltages. An internal 750kHz gated oscillator makes it ideal for space-limited designs. The 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.
- Adaptable duty cycle for battery or wide-input, voltage-range applications
- Capable of SEPIC and Flyback topologies
- Shutdown control with IQ
0.1µA (typical) - Low operating quiescent current IQ 120µA
- Voltage feedback tolerance (0.6% typical)
- Peak current limit feature
Applications
Consumer Electronics, Power Management
