TDA21475 exposed-top power stage contains a low quiescent-current synchronous buck gate-driver IC co-packaged with a Schottky diode, high-side and low-side MOSFETs. The package is optimized for PCB layout, heat transfer, driver/MOSFET control timing, and minimal switch node ringing. The gate driver and MOSFET combination enables higher efficiency at the lower output voltages required by cutting edge CPU, GPU and DDR memory designs.

Features

  • Co-packaged driver and Schottky diode
  • Co-packaged high-side & low-side MOSFETs
  • 5-mV/A on-chip MOSFET current sensing
  • Input voltage (VIN) range of 4.25-16 V
  • VCC & VDRV supply of 4.25-5.5 V
  • Output voltage range 0.25-5.5 V
  • 70 A output OCP capability
  • Operation up to 1.5 MHz
  • VCC/VDRV under voltage lockout (UVLO)
  • Bootstrap capacitor UVP
  • 8-mV/°C temperature analog output
  • Thermal shutdown and fault flag

Benefits

  • Higher efficiency at lower out voltages
  • Robustness and reliability
  • Optimized PCB layout, heat & transfer
  • Optimized driver/MOSFET control timing
  • Minimal switch node ringing
