Overview
The TPS54613PWP, produced by Texas Instruments, is a part of the SWIFT™ family of dc/dc regulators. This device is a low-input voltage, high-output current synchronous buck PWM converter designed to integrate all required active components on a single substrate. It operates with an input voltage range of 3V to 6V and can deliver up to 6A of continuous output current. The TPS54613PWP is housed in a thermally enhanced 28-pin HTSSOP (PWP) PowerPAD™ package, which helps in reducing board area and eliminating the need for bulky heatsinks. This converter is ideal for applications requiring high efficiency, fast transient response, and minimal component count.
