TPS5430 in TI TPS6xxxx Bucks & Boosts Family
The TPS5430 is a member of the Texas Instruments SWIFT family, specifically a high-output-current PWM converter that integrates a low-resistance N-channel MOSFET. This synchronous buck regulator supports an input voltage range from 5.5V to 36V, providing a constant 3A output. Designed for high efficiency and minimal external component counts, it utilizes a fixed 500 kHz switching frequency to balance efficiency with inductor size, making it a staple for industrial and consumer power management.
Variants in This Sub-Family
Variants within this sub-family primarily differ in their package options and thermal ratings. While the standard TPS5430 is available in an 8-pin SOIC package with an integrated PowerPAD for enhanced heat dissipation, other members of the broader TPS54x0 series scale the output current. For instance, the TPS5410 and TPS5420 provide 1A and 2A respectively, sharing the same pinout to allow engineers to scale power requirements without redesigning the PCB layout.
