TPS54218EVM-511

TEXAS INSTRUMENTS  TPS54218EVM-511  评估模块, TPS54218EVM-511

The is an evaluation module designed to evaluate the TPS54218 SWIFT DC/DC converter. The TPS54218 dc/dc converter is designed to provide up to a 2A output from an input voltage source of 2.95V to 6V. This evaluation module is designed to demonstrate the small PCB areas that may be achieved when designing with the TPS54218 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 1000KHz. The high side and low side MOSFETs are incorporated inside the TPS54218 package allowing for compact designs with minimal external circuitry. The low drain to source on resistance of the internal MOSFETs allows the TPS54218 to achieve high efficiencies and helps to keep the temperature low at high output currents. The TPS54218 is a full featured device including undervoltage lockout, adjustable slow start timing, adjustable switching frequency, enable, and power good functions.
