The TDA21462 power stage contains a low quiescent-current synchronous buck gate-driver IC co-packaged with Schottky diode, and high-side and low-side MOSFETs. The TDA21462 power stage forms a complete low voltage, high power DC/DC regulator when used with Infineon multiphase controller ICs. The TDA21462 internal MOSFET current sense algorithm with temperature compensation achieves superior current sense accuracy versus best-in-class controller-based inductor DCR sense methods. Operation at switching frequency as high as 1.5 MHz enables high performance transient response, allowing reduction of output inductance and output capacitance while maintaining industry leading efficiency.

Features

  • 5-mV/A on-chip MOSFET current reporting
  • Input voltage range of 4.25 V to 16 V
  • Vcc & Vdrv supply of 4.25 V to 5.5 V
  • Output voltage range from 0.25-5.5 V
  • 60A operating current with 70 A OCP
  • Operation up to 1.5 MHz
  • 8-mV/°C temperature analog output
  • Thermal shutdown and fault flag
  • Cycle-by-cycle programmable OCP
  • MOSFET phase fault detection and flag
  • Deep-sleep mode for power saving
  • Compatible with 3.3V tri-state PWM input

Benefits

  • High efficiency at low o/p voltage
  • Current & temperature monitoring
  • Bootstrap cap auto-replenishment
  • Optimized PCB heat transfer
