1.3 Description

TPSI3050Q1EVM allows users to easily switch between the two operational modes for evaluation. The EVM is designed with the flexibility to add Common Mode Chokes to minimize EMI. Figure 1-2 shows the functional block diagram for the isolated switch. The TPSI3050-Q1 is able to generate a floating secondary supply of 10-V with a 1.5-A peak source current and 3-A peak sink current. In addition, TPSI3050-Q1 supports two operation modes: two-wire and three-wire mode. In two-wire mode, the EN pin provides the power on the primary side. Use three-wire mode for applications that require higher levels of power transfer and the fastest enable and disable switch times the TPSI3050-Q1 can offer.

Available in three-wire mode only, the TPSI3050S features a one-shot enable for the switch control. This feature is useful for driving SCRs that typically require only one pulse of current to trigger.
