The MPQ8633A is a fully integrated, high-frequency, synchronous buck converter.

Product Detail

The MPQ8633A is a fully integrated, high-frequency, synchronous buck converter. It offers a very compact solution to achieve up to 12 A output current over a wide input supply range with excellent load and line regulation. The MPQ8633A operates at high efficiency over a wide output current load range. The MPQ8633A adopts internally compensated constant-on-time (COT) control mode that provides fast transient response and eases loop stabilization. The operating frequency is set easily to 600 kHz, 800 kHz, or 1000 kHz with the MODE configuration, allowing the MPQ8633A frequency to remain constant regardless of the input/output voltages. The output voltage start-up ramp is controlled by an internal 1 ms timer. It can be increased by adding a capacitor on TRK/REF. An open-drain power good signal indicates the output is within its nominal voltage range. The PGOOD is clamped to around 0.7V with external pull-up voltage when the input supply fails to power the MPQ8633A. Fully integrated protection features include OCP, OVP, UVP, and OTP. The MPQ8633A requires a minimum number of readily available, standard, external components and is available in a QFN 3mm x 4mm package.
