MIC2111 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 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...
