This user's guide contains background information for the TPS54202H as well as support documentation for the TPS54202HEVM-716 evaluation module (PWR716-001). Also included are the performance specifications, the schematic, and the bill of materials for the TPS54202HEVM-716.

The TPS54202H dc/dc converter is designed to provide up to a 2-A output from an input voltage source of
4.2 V to 28 V. Rated input voltage and output current range for the evaluation module are given in Table 1-1. This evaluation module is designed to demonstrate the small printed-circuit-board areas that may be achieved when designing with the TPS54202H regulator. The switching frequency is internally set at a nominal 500 kHz. The high-side and low-side MOSFETs are incorporated inside the TPS54202H package along with the gate-drive circuitry. The low drain-to-source on resistance of the MOSFETs allow the TPS54202H 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 TPS54202H provides an adjustable undervoltage lockout input. The absolute maximum input voltage is 30 V for the TPS54202HEVM-716.
