Description

The STPRDC01 smart driver implements a control scheme specific to secondaryside

synchronous rectification in STVCOT™-based resonant / non-resonant

converters.

It provides two high current gate drive outputs, each capable of driving one or more

N-channel Low-Side Power MOSFETs. Both gate driver are controlled by the

combination of START input and the embedded predictive ZCD/ZVS control assuring

the two external power MOSFETs to be switched in zero-voltage / zero-current

conditions to achieve high efficiency power conversion.

High-Impedance mode can be configured with the two external Power MOSFETs

immediately kept OFF.

The STPRDC01 is available in DFN12, 3x3 mm package with exposed pad.

Application

• High current high performance Step-Down conversion
