TPS5430MDDAREP 3A Step-Down Converter 1 Output 3A
The TPS5430MDDAREP is an enhanced product (EP) version of TI's SWIFT™ family of DC/DC regulators, designed as a high-output-current pulse-width modulation (PWM) step-down converter for demanding industrial, aerospace, and defense applications. It integrates a low-resistance high-side N-channel MOSFET, delivering robust performance across a wide input voltage range from 5.5V to 36V, supporting up to 3A continuous (4A peak) output current. The chip operates at a fixed 500kHz switching frequency, enabling compact filter designs, and is housed in a thermally enhanced 8-pin SOIC PowerPAD™ package for efficient heat dissipation. With a wide operating temperature range of -55°C to 125°C, it is engineered for reliability in harsh environments, offering controlled baseline, extended product life cycle, and traceability for critical systems.
The TPS5430MDDAREP is ideal for industrial and car audio power supplies, battery chargers, high-power LED drivers, and 12V/24V distributed power systems. It is well-suited for high-density point-of-load regulators in set-top boxes, DVD players, LCD displays, and plasma screens. Its enhanced specifications make it suitable for defense, aerospace, and medical applications requiring high reliability, extended temperature range, and controlled manufacturing processes.
