Datasheet Summary
Single-Phase, Multi-Mode, High-Performance, Step-Down PWM Controller PRELIMINARY
General 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 patible 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...
