MIC26600
7A Hyper Speed Control TM
Synchronous DC-DC Buck Regulator
SuperSwitcher II TM
General Description
Features
The Micrel MIC26600 is a constant-frequency, synchronous
buck regulator featuring a unique digitally modified adaptive
ON-time control architecture. The MIC26600 operates over
an input supply range of 4.5V to 26V and provides a
regulated output at up to 7A of output current. The output
voltage is adjustable down to 0.8V with a typical accuracy of
±1%, and the device operates at a switching frequency of
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 MIC26600 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-
circuit protection and thermal shutdown.
