Introduction
The TPS54526 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 TPS54526 package along with the gate drive circuitry.
The low drain-to-source on resistance of the MOSFETs allow the TPS54526 to achieve high efficiencies
and helps keep the junction temperature low at high output currents. The TPS54526 also has an auto-skip
Eco-mode™ to enable higher efficiency at light loads. The TPS54526 dc/dc synchronous converter is
designed to provide up to a 5.5-A output from an input voltage source of 4.5V to 18V. The output voltage
range is from 0.76V to 5.5V. The voltage and output current ranges for the evaluation module are given in
