TPS54622EVM-012

TEXAS INSTRUMENTS  TPS54622EVM-012  评估模块, TPS54622EVM-012

The is an evaluation module for TPS54622 synchronous step down SWIFT Converter. The TPS54622 dc/dc converter is designed to provide up to a 6A output. The TPS54622 implements split input power rails with separate input voltage inputs for the power stage and control circuitry. The power stage input PVIN is rated for 1.6V to 17V whereas the control input VIN is rated for 4.5V to 17V. This evaluation module is designed to demonstrate the small printed circuit board areas that may be achieved when designing with the TPS54622 regulator. The switching frequency is externally set at a nominal 480KHz. The high side and low side MOSFETs are incorporated inside the TPS54622 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFET allows the TPS54622 to achieve high efficiencies and helps keep the junction temperature low at high output currents. TPS54622 provides adjustable slow start, tracking, and undervoltage lockout inputs.
