Introduction

1 Introduction
This user's guide contains background information for the TPS54202 as well as support documentation for
the TPS54202EVM-716 evaluation module (PWR716-001). Also included are the performance

specifications, the schematic, and the bill of materials for the TPS54202EVM-716.

1.1 Background
The TPS54202 dc/dc converter is designed to provide up to a 2-A output from an input voltage source of
8 V to 28 V. Rated input voltage and output current range for the evaluation module are given in
In order to reduce EMI, the TPS54202 introduces frequency spread spectrum. The jittering span is ±6% of
the switching frequency with 1/512 swing frequency. This evaluation module is designed to demonstrate
the small printed-circuit-board areas that may be achieved when designing with the TPS54202 regulator.
The switching frequency is internally set at a nominal 500 kHz. The high-side and low-side MOSFETs are
incorporated inside the TPS54202 package along with the gate-drive circuitry. The low drain-to-source on
resistance of the MOSFETs allow the TPS54202 to achieve high efficiencies and helps keep the junction
temperature low at high output currents. The compensation components are integrated to the integrated
circuit (IC), and an external divider allows for an adjustable output voltage. Additionally, the TPS54202
provides an adjustable undervoltage lockout input. The absolute maximum input voltage is 30 V for the
TPS54202EVM-716.
