MIC2111 - Single-Phase Multi-Mode High-Performance Step-Down PWM Controller

Datasheet Summary

Description

Micrel’s MIC2111 is a programmable-frequency, valleycurrent/voltage-mode PWM controller that provides the control and protection

Features

  • necessary for a highcurrent, step-down DC-to-DC converter. The MIC2111 is compatible with power devices and drivers which use current sensing across the inductor. MIC2111 can provide single tri-state or dual non-tri-state PWM logic signals to work with either power-stage modules or discrete driver MOSFETs. MIC2111 has precision enable and power good (PG) functions for sequencing of multiple power supply. The MIC2111 frequency can be programmed from 200kHz to 2MHz to optimize system size and syst.
