TEXAS INSTRUMENTS  TPS54620RGYT  DC-DC Switching Buck Step Down Regulator, Adjustable, 4.5V-17Vin, 800mV-15Vout, 6Aout, QFN-14

Product Overview

The TPS54620RGYT is a 17V 6A Synchronous Step-down SWIFT™ 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 start-up ramp is controlled by the SS/TR pin which allows operation as either a standalone 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.
  • Integrated 26/19mΩ MOSFETs
  • Split power rail (1.6 to 17V on PVIN)
  • 200kHz to 1.6MHz Switching frequency
  • Synchronizes to external clock
  • 0.8V ±1% Voltage reference over-temperature
  • Low 2µA shutdown quiescent current
  • Monotonic start-up into pre-biased outputs
  • Adjustable slow start/power sequencing
  • Power good output monitor for under-voltage and overvoltage
  • Adjustable input under-voltage lockout
  • Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
