MP8792GLE
DESCRIPTION
The MP8792 is a fully integrated, highfrequency, synchronous buck converter. It offers a pact solution to achieve up to 12A of output current over a wide input supply range with excellent load and line regulation. The MP8792 operates at high efficiency over a wide output current load range.
The MP8792 adopts internally pensated constant-on-time (COT) control to provide fast transient response and ease loop stabilization.
The operating frequency can be set to 600k Hz, 800k Hz, or 1000k Hz with MODE configuration, allowing the MP8792’s frequency to remain constant regardless of the input or output voltages.
The output voltage start-up ramp is controlled by an internal 1ms timer. It can be increased by adding a capacitor on TRK/REF. An open-drain power good (PG) signal indicates whether the output is within its nominal voltage range. The PGOOD pin is clamped to about 0.7V by an external pull-up voltage when the input supply fails to power the MP8792.
