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.
