NCV8925 3 MHz, 600 mA Step-Down DC-DC Converter High-Efficiency, Low Ripple, Adjustable Output Voltage The NCV8925 DC-DC buck converter is available in a space saving low profile TSOP-5 and mUDFN6 package.

The part can supply output voltages from 0.9 V to 3.3 V by an external resistor divider and is able to deliver output currents up to 600 mA.

This switching regulator operates at 3.0 MHz and automatically switches between PFM and PWM modes to improve system efficiency.

Soft-start, cycle-by-cyc
