Product Overview

TDA21535AUMA1 is a 35A OptiMOS™ power stage with integrated current sense. It contains a low quiescent-current synchronous buck gate-driver IC co-packaged with high-side and low-side MOSFETs and an active diode structure that achieves low Vsd similar to a Schottky with very little reverse recovery charge. This power stage forms a complete low voltage, high power DC/DC regulator when used with Infineon multiphase controller ICs. The 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 a switching frequency as high as 1.5MHz enables high-performance transient response, allowing reduction of output inductance and output capacitance while maintaining industry-leading efficiency. Potential applications are high frequency, low profile DC/DC converters, voltage regulators for CPUs, GPUs, DDR memory arrays, computing servers, telecom, datacom, and graphics.
  • Higher efficiency at the lower output voltages enabled by the gate driver and MOSFET combination
  • Accurate current reporting to improve system level performance
  • Current and temperature fault monitoring for a more robust system
  • Bootstrap capacitor under-voltage monitoring and auto-replenishment for a more robust system
  • Input voltage (Vin) range of 4.25V to 16V, VCC and VDRV supply of 4.25V to 5.5V
  • High-side MOSFET short detection and flag, auto-sleep and deep-sleep mode for power saving
  • Cycle-by-cycle over current protection and fault flag, thermal shutdown
  • Compatible with 3.3V tri-state PWM input
  • On-chip MOSFET current sensing and reporting with 5µA/A gain
  • PQFN package, -40 to 125°C temperature range
