Datasheet Summary
High-Performance, Multi-Mode, Step-Down Controller
General Description
Micrel’s MIC2111B is a programmable-frequency, valleycurrent/voltage-mode PWM controller that provides the control and protection Features necessary for power devices and drivers that use current sensing across the inductor. The MIC2111B can provide single tri-state PWM logic signal to work with either power-stage modules or discrete driver and MOSFETs. The device has precision enable and power-good (PG) functions for sequencing of multiple power supplies. In addition, the solution is patible with intelligent power stages in a high-current, step-down DC/DC converter.
