DESCRIPTION
The MP8792 is a fully integrated, highfrequency,
synchronous buck converter. It
offers a compact 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 compensated
constant-on-time (COT) control to provide fast
transient response and ease loop stabilization.
The operating frequency can be set to 600kHz,
800kHz, or 1000kHz 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.
Fully integrated protection features include overcurrent
protection (OCP), over-voltage protection
(OVP), under-voltage protection (UVP), and overtemperature
protection (OTP).
The MP8792 requires a minimal number of
readily available, standard external components.
It is available in a QFN (3mmx4mm) package.
