Product Overview

The TPS54620RGYR is a synchronous Step-down Converter optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings are achieved through current-mode control, which reduces component count and by selecting a high switching frequency, reducing the inductor's footprint. The output voltage startup ramp is controlled by the SS/TR pin which allows operation as either a stand-alone power supply or in tracking situations. Power sequencing is also possible by correctly configuring the enable and the open drain power good pins. Cycle-by-cycle current limiting on the high-side FET protects the device in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. There is also a low-side sinking current limit which turns off the low-side MOSFET to prevent excessive reverse current. Thermal shutdown disables the part when die temperature exceeds thermal shutdown temperature.
  • Synchronizes to external clock
  • Monotonic start-up into pre-biased outputs
  • Adjustable slow start/power sequencing
  • Power good output monitor for undervoltage and overvoltage
  • Adjustable input undervoltage lockout
  • Supported by SwitcherPro™ software tool
  • Integrated 26/19mΩ MOSFETs
  • 0.8V ±1% Voltage reference over temperature
  • 2µA Low shutdown quiescent current
  • Green product and no Sb/Br
