Product overview

Description

The STPRDC01 smart driver implements a control scheme specific to secondary-side 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.

  • All features

    • Dual low-side driver for N-Channel MOSFETs
    • 4 A sink/source current
    • Operating frequency up to 1 MHz
    • Predictive ZCS / ZVS control
    • High-impedance control
    • START input
    • DFN12, 3x3 mm package
