TPS54202H in TI TPS6xxxx Bucks & Boosts Family
The TPS54202H is a high-efficiency synchronous buck converter family from Texas Instruments, engineered for step-down voltage regulation in industrial and consumer electronics. Operating from a wide 4.5V to 28V input range, these devices utilize a fixed 500kHz switching frequency to balance efficiency and magnetics size. Integrated high-side and low-side MOSFETs minimize external component count while the peak current mode control ensures stable operation and fast transient response for sensitive digital loads.
Variants in This Sub-Family
The TPS54202H variant is specifically characterized by its high-side MOSFET current limit and startup behavior tailored for higher reliability under heavy capacitive loads. While closely related to the standard TPS54202, the 'H' designation often denotes specific internal timing optimizations or protection thresholds. Most variations in this sub-family focus on packaging, such as the 6-pin SOT-23 (DDC) format, and differences in Pulse Skip Mode behavior for light-load efficiency.
