TPS54240EVM-605

TEXAS INSTRUMENTS  TPS54240EVM-605  评估板, 降压转换器

The is an evaluation module designed to evaluate TPS54240 dc/dc converter to provide up to 2.5A output from an input voltage source of 3.5V to 40V. This evaluation module is designed to demonstrate the small, printed circuit board areas that may be achieved when designing with the TPS54240 regulator. The switching frequency is internally set at a nominal 500kHz. The high side MOSFET is incorporated inside the TPS54240 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFET allows the TPS54240 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 TPS54240 provides adjustable slow start and undervoltage lockout inputs. The absolute maximum input voltage is 40V for the evaluation module.
