TPS561246DRLR product

TPS561246DRLR

PMIC - Voltage Regulators - DC DC Switching Regulators

synchronous buck1 A regulatorFCCM17 V inputSOT563

TPS561246DRLR is a 1 A synchronous buck regulator for 4.2 V to 17 V inputs, with integrated MOSFETs, FCCM operation and a compact 6-pin SOT563 package.

Best for

  • Compact point-of-load power supplies
  • WLAN, modem and router power rails
  • Applications requiring nearly constant switching frequency at light load

Avoid if

  • The input voltage is below 4.2 V or above 17 V
  • The design requires operation above 1 A continuous output current
  • Very high light-load efficiency is more important than fixed-frequency behavior

Check before use

  • Inductor saturation and RMS-current ratings
  • Effective, derated output capacitance
  • PCB thermal resistance and SW-node routing
  • Feedback-divider and optional feed-forward capacitor values
