1 Introduction

The TPS51386 is a single, D-CAP3™ control mode, synchronous buck converter requiring a very low external component count. The TPS51386 provides an adjustable 0.6-V to 5.5-V, 8-A maximum output. Integrated low RDS(ON) power MOSFETs enable high efficiency and offer ease of use with a minimal external component count for space-constrained power systems. Features include the following:

  • Accurate reference voltage
  • Fast load transient response
  • Auto-skip mode operation for light load efficiency
  • OOA light load operation with > 25-kHz switching frequency
  • D-CAP3 control mode with good line, load regulation, and no requirement for external compensation

The TPS51386 evaluation module (EVM) is a single, synchronous buck converter providing 5.1 V at 8 A from a 6-V to 24-V input. This user’s guide describes the TPS51386EVM performance.
