1MHz PWM Synchronous Buck Control IC General Description Features The MIC2168 is a high-efficiency, simple to use 1MHz PWM
synchronous buck control IC housed in a small MSOP-10
package. The MIC2168 allows compact DC/DC solutions
with a minimal external component count and cost.
The MIC2168 operates from a 3V to 14.5V input, without
the need of any additional bias voltage. The output voltage
can be precisely regulated down to 0.8V. The adaptive all
N-Channel MOSFET drive scheme allows efficiencies over
95% across a wide load range.
The MIC2168 senses current across the high-side N-Channel MOSFET, eliminating the need for an expensive and
lossy current-sense resistor. Current limit accuracy is maintained by a positive temperature coefficient that tracks the
increasing RDS(ON) of the external MOSFET. Further cost
and space are saved by the internal in-rush-current limiting
digital soft-start.
The MIC2168 is available in a 10-pin MSOP package, with a
wide junction operating range of –40°C to +125°C.
