MIC22950
10A Integrated Switch Synchronous
Buck Regulator with Frequency
Programmable to 2MHz General Description Features The Micrel MIC22950 is a high-efficiency 10A integrated
switch, synchronous buck (step-down) regulator. The
MIC22950 switching frequency is programmable from
400kHz to 2MHz, allowing the customer to optimize
designing either for efficiency or for the smallest footprint.
The MIC22950 achieves over 95% efficiency while still
switching at 2MHz over a broad load range.
The ultra-high-speed control loop keeps the output voltage
within regulation, even under extreme transient load
swings commonly found in FPGAs and low voltage ASICs.
The output voltage can be adjusted down to 0.7V in order
to address all low-voltage power needs.
The MIC22950 features a full range of sequencing and
tracking options. The EN/DLY and the DELAY pins,
combined with the POR/PG pin, allow multiple outputs to
be sequenced in several ways during turn-on and turn-off
by using EN pin. The RC (Ramp Controlв„ў) pin allows the
device to be connected to any another device in the
MIC22x00 family of products, to keep the output voltages
within a certain delta V during start-up. …
