Product Summary
The MIC2169ABMM is a high-efficiency, simple to use 500kHz PWM synchronous buck control IC housed in a small MSOP-10 package. It allows compact DC/DC solutions with a minimal external component count and cost. The MIC2169ABMM operates using a 3V to 14.5V input, without the need for any additional bias voltage. The output voltage can be precisely regulated down to 0.8V. The adaptive all N-Channel MOSFET drive scheme allows effi ciencies, over 95%, across a wide load range. The MIC2169ABMM 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 via a positive temperature coeffi cient that tracks the increasing RDS(ON) of the external MOSFET. Additional cost and space are saved by the internal in-rush-current limiting and digital soft-start. The MIC2169ABMM is available in a 10-pin MSOP package, with a wide junction operating range of –40℃ to +125℃.
