●The TPS54429EEVM-608 is an evaluation module for TPS54429E Synchronous Step Down Converter with auto skip eco mode. The TPS54429E is a single, adaptive on time DCAP2 mode synchronous buck converter requiring a very low external component count. The DCAP2 control circuit is optimised 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 700KHz. The high side and low side switching MOSFETs are incorporated inside the TPS54429E package along with the gate drive circuitry. The low drain to source on resistance of the MOSFETs allows the TPS54429E to achieve high efficiencies and helps keep the junction temperature low at high output currents. The TPS54429E dc/dc synchronous converter is designed to provide up to a 4.5A output from an input voltage source of 7V to 18V. The output voltage range is from 0.76V to 5.5V.
● DCAP2 mode enables fast transient response
