MIC2169A Description
The MIC2169A is a high-efficiency, simple to use 500kHz PWM synchronous buck control IC housed in a small MSOP10 package. The MIC2169Aallows pact DC/DC solutions with a minimal external ponent count and cost. The MIC2169A operates from a 3V to 14.5V input, without the need of any additional bias voltage.
