MIC2169 Datasheet | Micrel Semiconductor

Micrel 500kHz PWM Synchronous Buck Control IC General Description The MIC2169 is a high-efficiency, simple to use 500kHz PWM synchronous buck control IC housed in a small MSOP-10 package. The MIC2169 allows pact DC/DC solutions with a minimal external ponent count and cost. The MIC2169 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 efficiencies, over 95%, across a wide load range. The MIC2169 senses current across the high-side N-Channel MOSFET, eliminating the need for an expensive and lossy current-sense resistor....
