1 Introduction
This user's guide contains background information for the TPS54360 as well as support documentation for
the TPS54360EVM-182 evaluation module (PWR182). Also included are the performance specifications,
the schematic, and the bill of materials for the TPS54360EVM-182.
1.1 Background
The TPS54360 DC-DC converter is designed to provide up to a 3.5-A output from an input voltage source
of 4.5 V to 60 V. Rated input voltage and output current range for the evaluation module are given in
Table 1. This evaluation module is designed to demonstrate the small, printed-circuit-board areas that may
be achieved when designing with the TPS54360 regulator. The switching frequency is externally set at a
nominal 600 kHz. The high-side MOSFET is incorporated inside the TPS54360 package along with the
gate drive circuitry. The compensation components are external to the integrated circuit (IC), and an
external resistor divider allows for an adjustable output voltage. Additionally, the TPS54360 provides an
adjustable undervoltage lockout with hysteresis through an external resistor divider. The absolute
maximum input voltage is 60 V for the TPS54360EVM-182.
