TPS54340DDAR in TI TPS6xxxx Bucks & Boosts Family
The TPS54340DDAR belongs to the Texas Instruments Eco-Mode step-down regulator family, designed for high-voltage DC-DC conversion. This 42V, 3.5A buck converter utilizes an integrated high-side MOSFET and current mode control to simplify compensation and offer high transient response. It is engineered to maintain high efficiency across a wide load range, particularly in industrial and automotive environments where input voltage spikes and low-load efficiency are critical design constraints.
Variants in This Sub-Family
Variants in the TPS54340 sub-family primarily differ in their current ratings and qualification levels. While the TPS54340 supports up to 3.5A, the TPS54540 provides a footprint-compatible path for 5A requirements. Additionally, the TPS54340-Q1 variant is available for automotive applications, featuring AEC-Q100 qualification and specific testing for temperature grades and reliability standards necessary for under-the-hood environments.
