Description:
The MPQ8633B is a fully integrated, highfrequency, synchronous, buck converter. It offers a very compact solution that achieves up to 20A of output current with excellent load and line regulation over a wide input supply range.
The MPQ8633B operates at high efficiency over a wide output current load range. The MPQ8633B adopts an internally compensated constant-on-time (COT) control mode that provides fast transient response and eases loop stabilization.
The operating frequency can be set to 600kHz, 800kHz, or 1000kHz easily with MODE configuration, allowing the MPQ8633B frequency to remain constant regardless of the input and 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 (PGOOD) signal indicates if the output is within its nominal voltage range. PGOOD is clamped at around 0.7V with an external pull-up voltage when the input supply fails to power the MPQ8633B.
Full protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-temperature protection (OTP).
The MPQ8633B requires a minimal number of readily available, standard, external components and is available in a QFN-21 (3mmx4mm) package.
