It offers a very compact solution to achieve 4A/6A/8A/10A/12A/15A/20A output current over a wide input supply range with excellent load and line regulation. The MPQ8632 uses Constant-On-Time (COT) control mode to provide fast transient response and ease loop stabilization. An external resistor programs the operating frequency from 200kHz to 1MHz and the frequency keeps nearly constant as input supply varies with the feedforward compensation. The default under voltage lockout threshold is internally set at 4.1V, but a resistor network on the enable pin can increase this threshold. The soft start pin controls the output voltage startup ramp. An open drain power good signal indicates that the output is within nominal voltage range. It has fully integrated protection features that include over-current protection, over-voltage protection and thermal shutdown. The MPQ8632 requires a minimal number of readily available standard external components and is available in a 16-Pin QFN 3mm×4mm or a 29-Pin QFN 5mm×4mm package.
