●The TPS54327EVM-686 is a fully assembled and tested circuit for evaluating the TPS54327 synchronous step down SWIFT Converter. The evaluation module operates from a 4.5V to 18V input and provides a 1.05V output at 3A.The TPS54327 is a single, adaptive on time, D CAP2 mode, synchronous buck converter requiring a very low external component count. The D CAP2 control circuit is optimized for low ESR output capacitors such as POSCAP, SP CAP, or ceramic types and features fast transient response with no external compensation. The switching frequency is internally set at a nominal 700 kHz. The high side and low side switching MOSFETs are incorporated inside the TPS54327 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFETs allows the TPS54327 to achieve high efficiencies and helps keep the junction temperature low at high output currents.
● D-CAP2 mode enables fast transient response
● Low output ripple and allows ceramic output capacitor
● Wide Vin input voltage range from 4.5V to 18V
● Output voltage range from 0.76 V to 5.5V
● Highly efficient integrated FETs optimized for lower duty cycle applications
● High efficiency, less than 10uA at shutdown
● High initial band gap reference accuracy
