The TPS65121RGTT is a switch-mode power supply from Texas Instruments. It is a Special Purpose Voltage Regulator component of the PMIC (Power Management IC) product family. This device integrates power MOSFETs, linear regulator, gate drivers, and a bidirectional, low-side gate drive fault output pin, to form a power module for high-power, isolated power system applications. It can support output currents up to 350 mA in buck topology, 180mA in buck-boost topology, and 160mA in flyback topology.

The TPS65121RGTT utilizes a Vin pin to supply the power to the output and the feedback circuitry. The feedback input voltage is determined by the voltage source to which the output voltage is compared. The output voltage is adjustable by means of the FB pin. When the output voltage is above or below the preset value, a current flows the FB pin to reach the desired output voltage. The output voltage is monitored by a comparator that triggers the windows comparator threshold and drives the error flag output pin.

The TPS65121RGTT\'s solution offers high efficiency, advanced line-regulation, fast load transients, system-level protection, and diagnostics. It also integrates a current sense feedback circuit to auto adjust the MOSFET switching frequency to optimize efficiency and reduce EMI. This device is well suited for power management for industrial isolation system and for driving higher loads in high-critical applications.

The TPS65121RGTT utilizes a wide range of switching frequencies from 1.2 kHz to 1.2 MHz with the frequency set by a resistor. Due to the low-side gate drive fault output pin, if there is an internal fault, the pin will be asserted low to provide fail safe information to the system. In addition, the TPS65121RGTT also offers an enable pin that allows you to enable or disable the output as needed. It can also be configured to a low-battery operation mode to reduce power dissipation.

The TPS65121RGTT is an ideal solution for isolated power supply needs in various applications including isolated DC/DC converters, industrial control systems, communication systems, embedded systems and remote diagnostics. It is a cost effective and power efficient solution for today’s demanding high voltage and power management requirements. Moreover, it has the ability to provide effective protection from over-voltage, ESD, over-current and short-circuit.
