MIC2111
Overview
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.
- Single 3.3V or 5V supply
- Supports load currents more than 50A
- Programmable valley-current/voltage-mode PWM architecture
- 3.3V logic PWM outputs compatible with power-stage modules and DrMOS modules
- Single tri-state PWM output
- Programmable switching f
