ME2188

microne

Efficient PFM synchronous boost DC-DC conversion chip

summary

ME2188 is a series of high conversion efficiency, low power consumption, and high operating frequency

PFM synchronous boost DC-DC conversion chip. The chip utilizes PFM control

Circuit that automatically switches the duty ratio coefficient according to the magnitude of the load current to achieve low

A series of products with ripple, high efficiency, and wide output voltage range. In-chip

Low current consumption of synchronous switching tubes and chips effectively improves DC-DC

Conversion efficiency and equipment life cycle. Only three components are needed for the periphery

It is possible to boost the low input battery voltage to the required operating voltage.
