Monolithic Power Systems MPQ8632D High Efficiency Step-Down Converters

Monolithic Power Systems MPQ8632D
High Efficiency Step-Down Converters

Monolithic Power Systems MPQ8632D High Efficiency Step-Down Converters are fully integrated, high frequency, synchronous rectified step-down switch mode converters designed to achieve 4A/6A/8A/10A/12A/15A/20A output current over a wide input supply range with excellent load and line regulation. MPQ8632D's fully integrated protection features include over-current protection, over-voltage protection, and thermal shutdown. Using Constant-On-Time (COT) control mode, MPQ8632D offers a 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. Though the default under voltage lockout threshold is internally set at 4.1V, 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. These features make the MPQ8632D High Efficiency Step-Down Converters well-suited for telecom & networking systems, base stations, servers, personal video recorders, flat panel television & monitors, and distributed power systems.
