Introduction
The TPS54525 is a single, adaptive on-time, D-CAP2™-mode, synchronous buck converter requiring a
very low external component count. The D-CAP2™ control circuit is optimized for low-ESR output
capacitors such as POSCAP, SP-CAP, or ceramic types and features fast transient response with no
external compensation. The switching frequency is internally set at a nominal 650 kHz. The high-side and
low-side switching MOSFETs are incorporated inside the TPS54525 package along with the gate drive
circuitry. The low drain-to-source on resistance of the MOSFETs allow the TPS54525 to achieve high
efficiencies and helps keep the junction temperature low at high output currents. The TPS54525 dc/dc
synchronous converter is designed to provide up to a 5.5-A output from an input voltage source of 4.5 V to
18 V. The output voltage range is from 0.76 V to 5.5 V. Rated input voltage and output current ranges for
the evaluation module are given in
