The MIC2169B is a high-efficiency, simple to use 500kHz PWM synchronous buck control IC housed in a small MSOP-10 ePad package. It allows compact DC/DC solutions with a minimal external component count and cost. The device features high output driver capability to drive loads up to 30A. The MIC2169B 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 within the smallest possible printed circuit board space area.The MIC2169B 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 MIC2169B is identical to the MIC2169A except it supports pre-bias loads. Internal pre-bias circuit prevents output voltage drooping and excessive reverse inductor current when powering up with a pre-bias voltage at the output. The MIC2169B is available in a 10-pin MSOP and a thermally-capable 10-pin ePad MSOP package, with a wide junction operating range of -40°C to +125°C.
