MIC2176-1/-2/-3
Wide Input Voltage, Synchronous Buck
Controllers Featuring Adaptive On-Time
Control
Hyper Speed Control? Family
General Description
Features
The Micrel MIC2176-1/-2/-3 is a family of constant-frequency,
synchronous buck controllers featuring a unique digitally
modified adaptive ON-time control architecture. The MIC2176
family operates over an input supply range of 4.5V to 75V
and can be used to supply up to 15A of output current. The
output voltage is adjustable down to 0.8V with a guaranteed
accuracy of ±1%, and the device operates at a constant
switching frequency of 100kHz, 200kHz, and 300kHz.
Micrel’s Hyper Speed Control TM architecture allows for ultra-
fast transient response while reducing the output capacitance
and also makes (High V IN )/(Low V OUT ) operation possible.
This digitally modified adaptive t ON ripple control architecture
combines the advantages of fixed-frequency operation and
fast transient response in a single device.
The MIC2176 offers a full suite of protection features to
ensure protection of the IC during fault conditions. These
include undervoltage lockout to ensure proper operation
under power-sag conditions, internal soft-start to reduce
inrush current, fold-back current limit, “hiccup” mode short-
