Description
View TPS40021EVM-001
The TPS4002x family of devices are low-input voltage synchronous, voltage-mode buck controllers. Built upon the TPS40000 products, the TPS4002x family provides enhanced operation and design flexibility through user programmability. The uses of the predictive gate drive and charge pump/boost circuits combine to provide a highly efficient, smaller and less expensive converter. It can be widely used in networking equipment, servers, base stations, DSP power, and telecommunication applications. The datasheet describes the functionalities of the controller in more detail. This User’s Guide describes the TPS40021EVM−001 evaluation module (HPA009), a step-down application from 3.3 V to 1.5 V with the TPS400021 PWM controller.
