产品概览
The MPQ8633BGLE-Z is a Monolithic Power Systems (MPS) 16V, 20A fully integrated synchronous step-down converter with adjustable current limit, configurable frequency, and voltage tracking. It adopts internally compensated constant-on-time (COT) control to provide fast transient response and ease loop stabilization. The switching frequency can be set to 600kHz, 800kHz, or 1000kHz via MODE configuration. Available in a QFN-21 (3mm x 4mm) package.
