Monolithic Power Systems (MPS) MPQ2178 Synchronous Step-Down Converters are monolithic and switch-mode converters with internal built-in power MOSFETs. These converters achieve 2A of continuous output current across a 2.5V to 5.5V input voltage range with a good load and line regulation. The output voltage (VOUT) of the MPQ2178 synchronous step-down converters can be regulated to as low as 0.6V for the adjustable output version. These converters feature 1% Feedback (FB) accuracy, 2.4MHz switching frequency, fixed output options, 100% duty cycle, and external Soft Start (SS) control.
The MPQ2178 synchronous step-down converters use a Constant-On-Time (COT) control with input voltage feed-forward to stabilize the Switching Frequency (fSW) across the full input range. Typical applications include automotive infotainment, camera modules, key fobs, industrial supplies, and battery-powdered devices.
