TPS566231P 6-A synchronous step-down converter with PGOOD evaluation module


Order now


The TPS566231PEVM is used to evaluate the TPS566231P device, a high-voltage input, synchronous buck converter with integrated FETs.  One of the key features of the TPS566231P is its ULQ (ultra low quiescent) to enable low-bias current. This feature is extremely beneficial for long battery life in low power operation. The TPS566231P operates with wider supply input voltage ranging from 3 V to 18 V. It uses DCAP3™ control mode to provide a fast transient response, good line, load regulation, no requirement for external compensation and supports low ESR output capacitors. The TPS566231P is a high-efficiency converter and provides complete protection OVP, UVP, OCP, OTP and combined power-good signal.

  • 3-V to 18-V input voltage range
  • 0.6-V to 7-V output voltage range
  • Up to 6-A output current
  • PSM with high efficiency at light loading
  • PGOOD indicator
