TPS62134BRGTT Application Field and Working Principle

The Texas Instruments TPS62134BRGTT is a synchronous step-down power module (PMIC) used for a variety of applications. It is a DC-DC switching regulator capable of providing up to 15A of output current with a power conversion efficiency of up to 95%. The part is available in a thermally enhanced three-by-three-by-one-centimeter HV-SO package, making it ideal for space-constrained applications.

This PMIC is most frequently used to power microprocessors, FPGAs, ASICs, and other applications that require a low voltage, constant current supply. It is also suitable for a range of applications that require low output voltages, such as LED backlighting, MEMS sensors, and mobile devices. In addition, the TPS62134BRGTT is compliant with AEC-Q100 automotive standards, making it a good choice for automotive applications.

Working Principle

The TPS62134BRGTT is a synchronous buck converter with an operating frequency of 2 MHz to 4 MHz. The part utilizes an internal high-side MOSFET and low-side MOSFET for power conversion, and has a wide input voltage range of 3.2 V to 14 V. The output voltage is adjustable and can be set between 0.6 V and 5.5 V.

The part features cycle-by-cycle current-limit protection, as well as input and output undervoltage protection. Additionally, the TPS62134BRGTT includes a soft-start time of 300 ps, allowing the output voltage to ramp up slowly, thus minimizing inrush current.

The part is able to deliver continuous output currents of up to 15A, making it a good choice for high-power applications such as FPGAs and ASICs. The chip features a thread-shaped thermal pad that improves the heat dissipation and helps ensure the device remains cool during operation.
