It’s new year’s eve and I’m busy working away. Why you ask? Well, I’ve been fortunate enough to be the recipient of another RoadTest item – this time, it’s a Texas Instruments Evaluation Module.
The module in specific is the TPS56C215EVM-762, which is built around their TPS56C215 4.5V to 17V Input, 12-A Synchronous Step-Down SWIFT(tm) Converter. This is a 3.5mm x 3.5mm VQFN-18 chip requiring only passive external components to realize a high performance synchronous buck converter as it integrates a MOSFET within the package.
Features include adaptive-on-time D-CAP3 control mode with selectable Forced Continuous Conduction Mode (FCCM) or Auto-Skipping Eco-mode(tm) for high light-load efficiency. Other features include a 0.6v to 5.5v output voltage range, selectable switching frequency of 400khz, 800khz or 1.2Mhz, adjustable current limit settings, adjustable soft-start, enable pin, power-good signal and efficiencies up to 94% depending on the configuration. The chip also has overtemperature protection and undervoltage lockout, with output under/overvoltage protection features.
