TPS54332EVM-416 的說明
The TPS54332 dc/dc converter is designed to provide up to a 3.5 A output from an input voltage source of 3.5 V to 28 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 TPS54332 regulator. The switching frequency is internally set at a 1000 kHz. The high-side MOSFET is incorporated inside the TPS54332 package along with the gate drive circuitry. The low drain-to-source on resistance of the MOSFET allows the TPS54332 to achieve high efficiencies and helps keep the junction temperature low at high output currents. Thecompensation components are external to the integrated circuit (IC), and an external divider allows for an adjustable output voltage. Additionally, the TPS54332 provides adjustable slow start and undervoltage lockout inputs. The absolute maximum input voltage is 30 V for the TPS54332EVM-416.
