Background

Introduction
The switching frequency is set at a nominal 700 kHz, allowing the use of a
small footprint 0.65
μ
H output inductor. The MOSFETs of the SWIFT
regulators are incorporated inside the package. This eliminates the need for
external MOSFETs and their associated drivers. The low drain-to-source on
resistance of the MOSFETs gives the SWIFT
regulators high efficiency and
helps to keep the junction temperature low at high output currents. It is
important to note that the SWIFT
integrated FET dc/dc converters provide
true thermal protection of the whole circuit. Controllers utilizing external FETs
thermally protect only the controller itself, not the FETs. The compensation
components of TPS54x80 regulators are provided external to the IC, and allow
for an adjustable output voltage and a customizable loop response.

Input Voltage and Output Current Summary
EVM
Input Voltage Range
Output Current Range
TPS54680EVM-228
4.3 V to 6 V
0 A to 6 A
TPS54880EVM-228
4.5 V to 6 V
0 A to 8 A
The minimum input voltage in this EVM is limited by the 3.3 V output of regulator TPS54X10. The
input voltage should be always above the output voltage plus an additional margin because of
voltage drops in power stage and limited maximum duty cycle. The data sheet specifies the mini-
mum input voltage of TPS54680 regulator as 3 V. The minimum input voltage of TPS54880 regu-
lator is 4 V.
