TPS5211EVM-154

The TPS5211EVM-154 is a type of synchronous-buck converter evaluation module (SLVP154). The SLVP154 offers a convenient method for evaluating the performance of a synchronous-buck converter utilzing the TPS5211 high-fre quency programmable-hysteretic regulator controller. A completely designed and tested power supply is presented. The power supply is a 5-V to 1.65-V step-down dc-dc EVM that is able to deliver reach to 22 A of continuous output current and 26 A of peak transient current. TPS5211EVM-154 also included onboard is a 370-pin CeleronE microprocessor socket and a transient load generator. The PWB board layout offers test points for viewing waveforms.

The performance specifications of the TPS5210EVM-119 can be summarized as: (1)input voltage range(main power): 4.5V min and 13V max; (2)static voltage tolerance(VID inputs set for VREF=1.65V.): 1.57V min, 1.65V typ and 1.69V max; (3)line regulation(input voltage can be at any point over entire range):±0.05% typ and ±0.1% max; (4)tran sient response(IO pulsed from 2.2A to 26A, di/dt=30A/ms):-130mV pk min and 80mV pk max; (5)output current range: 0A min and 26A max; (6)current limit: 27A min; (7)output ripple: 24mV typ; (8)soft-start risetime: 10ms typ; (9)operating frequency: 120kHz min, 125kHz typ and 145kHz.
