... SiL PS-EVB Introduction The SiLinkPS-EVB is a system power supply board that provides all the necessary supply voltages for a variety of Silicon Laboratories’ ProSLIC and silicon DAA evaluation boards. When used with an appropriate ac/ dc wall adapter, the SiLinkPS-EVB can provide total output power. Table 1 lists some typical voltages and currents at the power supply outputs ...

... Resistor R23 can be modified to realize custom output voltages as defined in the following equation. VNEG = (1.23 x R23/R22) + 1.23 The SiLinkPS-EVB is shipped with R23 = 33.2 k and R22 = 1.65 k for VNEG equal The VBLO is normally used for off-hook state and its voltage level can be programmed by the setting on the Table 2 ...

... LT1375 IC operates at its internal fixed 500 kHz and is only synchronized with the LTC3704 frequency when it senses the frequency on the SYNC pin going above 550 kHz. The SiLinkPS-EVB power designed to operate safely with switching frequency on the LTC3704 ranging from 200 kHz to 1 MHz. Initialization Steps 1 ...
