TPS54317EVM-159

TEXAS INSTRUMENTS  TPS54317EVM-159  评估模块, TPS54317EVM-159

The is an evaluation module for TPS54317 synchronous buck converter. The TPS54317 dc/dc converter is designed to provide up to 3A output from an input voltage source of 3V to 6V. This evaluation module is designed to demonstrate the small PCB areas that may be achieved when designing with the TPS54317 regulator, and does not reflect the high efficiencies that may be achieved when designing with this part. The switching frequency is set at a nominal 1100KHz, allowing the use of a small footprint 1.5mH output inductor. The high and low side MOSFETs are incorporated inside the TPS54317 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFETs allows the TPS54317 to achieve high efficiencies and helps to keep the junction temperature low at high output currents. customizable loop . The TPS54317 provides a programmable undervoltage lockout, synchronization, adjustable switching frequency, enable, and power good functions.
