Introduction
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 TPS40021EVM001 evaluation
module (HPA009), a step-down application from 3.3 V to 1.5 V with the TPS400021 PWM
controller.
A schematic of the evaluation module is shown in Figure 1. A recommended parts list is
provided in Table 1. The layout of the PCB board is shown in Figure 9.
