SLVUAH4A August 2015 – October 2021 TPS54334
The TPS54334 dc/dc converter is designed to provide up to a 3-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 TPS54334 regulator. The switching frequency is externally set at a nominal 570 kHz. The high-side and low-side MOSFETs are incorporated inside the TPS54334 package along with the gate-drive circuitry. The low drain-to-source on resistance of the MOSFETs allow the TPS54334 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The compensation components are external to the integrated circuit (IC), and an external divider allows for an adjustable output voltage. Additionally, the TPS54334 provides an adjustable undervoltage lockout input. The absolute maximum input voltage is 30 V for the TPS54334EVM-722.
