TEST REPORT
160-A, Four-Phase Reference Design Using the TPS546D24A Integrated FET Converter
1 Description
The PMP21254 is designed for powering high-current, low-voltage ASICs and FPGAs from a 5-V or 12-V rail. The design is optimized for high-density, and supports PMBus with current, voltage and temperature telemetry, if desired. A test report is included.
