MIC2168 - 1MHz PWM Synchronous Buck Control IC Docket ↓MIC2168 Micrel, Inc. MIC2168 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.
