Overview

The NCP5351 is a dual MOSFET gate driver optimized to drive the gates of both high-side and low-side Power MOSFETs in a Synchronous Buck converter. The NCP5351 is an excellent companion to multiphase controllers that do not have integrated gate drivers. This architecture provides a power supply designer the flexibility to locate the gate drivers close to the MOSFETs. The 4 A drive capability makes the NCP5351 ideal for minimizing switching losses in MOSFETs with large input capacitance. Optimized internal, adaptive non-overlap circuitry further reduces switching losses by preventing simultaneous conduction of both MOSFETs.

  • Synchronous Buck Converters

  • Power Supplies

  • 4 A Peak Drive Current
  • Rise and Fall Times < 15 ns typical into 6000 pF
  • Propagation delay from Inputs to Outputs < 20 ns
  • Adaptive NonOverlap Time Optimized for Large Power MOSFETs
  • Floating Top Driver Accommodates Applications Up to 25 V
  • Undervoltage Lockout to Prevent Switching when the Input Voltage is Low
  • Thermal Shutdown Protection Against Overtemperature
  • < 1.0 mA Quiescent Current - Enabled
  • 25 µA Quiescent Current - Disabled
  • Internal TG to DRN Pulldown Resistor Prevents HV Supply-Induced Turn On of High-Side MOSFET
