Micrel MIC2168A
The MIC2168A is a high-efficiency, simple to use 1MHz PWM synchronous buck-control IC housed in a small MSOP-10 package. The MIC2168A allows compact DC/DC solutions with a minimal external component count and cost. The MIC2168A operates from a 3V to 14.5V input, without the need of any additional bias voltage.- Max Voltage : 14.5V
- Max Operating Temp : 125°C
- Min Operating Temp : -40°C

GENERAL DESCRIPTION
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 MIC2168A senses current across the high-side NChannel 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 and digital soft-start. The MIC2168A is identical to the MIC2168 with the exception that the MIC2168A increases t
