TPS628680ARQYR

Voltage Regulators - DC DC Switching Regulators

4 Asynchronous buckI2CDVS2.4 MHzVQFN-HR0.2 V to 0.8375 V

TPS628680ARQYR is a 4 A I2C-programmable synchronous buck regulator for 2.4 V to 5.5 V rails and low-voltage outputs from 0.2 V to 0.8375 V.

Best for

  • Low-voltage FPGA and ASIC rails
  • CPU core supplies
  • LPDDR5 VDDQ power rails
  • Compact 4 A point-of-load converters

Avoid if

  • Input voltage is outside 2.4 V to 5.5 V
  • Output requirement exceeds 0.8375 V
  • A non-I2C fixed-output regulator is required

Check before use

  • Startup resistor and assigned I2C target address
  • Inductor saturation-current margin
  • Effective output capacitance under DC bias
  • Thermal margin and layout
