ML4890 Datasheet (Micro Linear) - High Efficiency / Low Ripple Boost Regulator

ML4890, High Efficiency / Low Ripple Boost Regulator

The ML4890 is a high efficiency, PFM (Pulse Frequency Modulation), boost switching regulator connected in series with an integrated LDO (Low Dropout Regulator) that incorporates “Silent Switcher™” technology.

This technique incorporates a patented tracking scheme to minimize the voltage drop across

ML4890 Features

* s s Incorporates “Silent Switcher™” technology to deliver very low output voltage ripple (typically 5mV) Guaranteed full load start-up and operation at 1.0V input and low operating quiescent current (
