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.
