1 Introduction
The TPS51386 is a single, D-CAP3
component count. The TPS51386 provides an adjustable 0.6-V to 5.5-V, 8-A maximum output. Integrated low
R
power MOSFETs enable high efficiency and offer ease of use with a minimal external component count
DS(ON)
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.
