The SGM64201 is a 4.5V to 25V controller with adaptive constant on-time (ACOT) control for synchronous Buck converters. It is capable to efficiently drive two N-MOSFETs over the whole voltage range. The SGM64201 exports the maximize power and limits the maximum valley current of the low-side MOSFET. The forced pulse width modulation (FPWM) mode or power saving mode (PSM) at light load is configurable through the voltage of MODE pin.
Eight preset switching frequency can be selected by an external resistor between the RF pin and GND or between the RF pin and the VREG pin.
The SGM64201 is available in a Green TQFN-3×3-16FL package.
