MIC23201 - 2MHz PWM 2A Buck Regulator with Hyper Speed Control?
2MHz PWM 2A Buck Regulator with
Hyper Speed Controlâ„¢ General Description Features The MIC23201 is a high efficiency 2MHz 2A synchronous
buck regulator with Hyper Speed Control. Micrelâ€™s Hyper
Speed Control provides ultra-fast transient response which
is perfectly suited for supplying processor core voltages.
An additional benefit of this proprietary architecture is very
low output ripple voltage throughout the entire load range
with the use of small output capacitors. The tiny 3mm x
3mm MLFÂ® package saves precious board space and
requires only three external components.
The MIC23201 is designed for use with a very small
inductor, down to 1ÂµH, and an output capacitor as small as
22ÂµF that enables a total solution size, less than 1.5mm
The MIC23201 provides a constant switching frequency
around 2MHz while achieving peak efficiencies up to 90%.
The MIC23201 is available in 10-pin 3mm x 3mm MLF
package with an operating junction temperature range
from â€“40ï‚°C to +125ï‚°C.
