MPQ8632D-6 6A, 2.5-18V, DCM, Non-latch OVP, COT Synchronous Step-down Converter with output Discharge

Product Detail

The MPQ8632D-6/MPQ8632D-12 is a fully integrated high frequency synchronous rectified step-down switch mode converter. It offers a very compact solution to achieve 6A/12A output current over a wide input supply range with excellent load and line regulation. The MPQ8632D-6/MPQ8632D-12 operates at high efficiency over a wide output current load range. The MPQ8632D-6/MPQ8632D-12 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. An open drain power good signal indicates that the output is within nominal voltage range. The MPQ8632D-6/MPQ8632D-12 employs a programmable soft start and shut-down scheme. With the soft shut-down feature, it discharges the output voltage smoothly when the enable signal is deserted. It has fully integrated protection features that include over-current protection, over-voltage protection and thermal shutdown. The MPQ8632D-6/MPQ8632D-12 requires a minimal number of readily available standard external components and is available in a 3mm?mm package.
