General Description

Micrel MIC2111B’s is a programmable frequency, valley- -

current/voltage-mode PWM controller that provides the

control and protection features necessary for power

devices and drivers use current sensing across the that

inductor. The MIC2111B state can provide single tri- PWM

logic signal to work with either power stage modules or -

discrete driver The device has precision and MOSFETs.

enable and power functions for sequencing of -good (PG)

multiple power suppl In addition the solution ies. , is

compatible with intelligent power stages in a high-current,

step-down DC/DC converter.

To optimize system size and system efficiency, the

MIC2111B frequ ency can be programmed from 200kHz to

2MHz. The device operates in power-saving mode at light

loads by reducing udio rangefrequency. Optional outside a

operation the is possible when power-stage is configured

in light load mode. The solution uses different ial current

sensing for better current limit accuracy- and a dedicated

differential amplifier for remote output sensing for accurate

output voltage control. has a high The MIC2111B -gain

transconductance amplifier for loop compensation.

External slope compensation can added through be a

resistor to avoid sub-harmonic oscillations. Other features

include programmable OCP, output and thermal OVP,

OTP protections. The MIC2111B offers Micrel’s proprietary

bi-directional, single wire fault communication for total

system protection.

The MIC2111B 20-pis available in a in 3mm × 3mm TQ FN

package and has a junction temperature range of –40°C to

+125°C.
