TPS55340EVM-147 [Texas Instruments]

The TPS55340 is a DC/DC converter typically used as a step-up boost converter, but this evaluation module demonstrates its use in a SEPIC topology. It features an integrated 40V, 5A low-side MOSFET with low drain-to-source on-resistance for high efficiency. The switching frequency is externally set at 500 kHz. The device supports input voltages from 6V to 18V and can deliver up to 1A output current. Compensation components are external, allowing design flexibility. The evaluation module shows a compact PCB area design.
