Overview
The TPS54613PWPR is a part of the SWIFT™ family of dc/dc regulators from Texas Instruments. This device is a 3-V to 6-V input, 6-A output synchronous buck PWM converter, specifically designed with a fixed output voltage of 1.5V. It integrates all required active components, including high-performance voltage error amplifiers, an under-voltage-lockout circuit, and an internally and externally set slow-start circuit. The TPS54613PWPR is packaged in a thermally enhanced 28-pin HTSSOP (PWP) PowerPAD™ package, which eliminates the need for bulky heatsinks and reduces board area and total cost.
