Description

General part information

MIC2169A Series

The MIC2169A is a high-efficiency, simple to use 500kHz PWM synchronous buck control IC housed in a small MSOP-10 package. The MIC2169A allows compact DC/DC solutions with a minimal external component count and cost.

The MIC2169A 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 Channel MOSFET drive scheme allows efficiencies over 95% across a wide load range.

The MIC2169A 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.
