The TPS5120 from Texas Instruments is a dual-channel, high-efficiency synchronous buck controller designed for versatile power management applications. This controller features outputs that operate 180 degrees out of phase, which effectively reduces input current ripple and lowers the required input capacitance.
Key electrical specifications include a wide input voltage range from 4.5 V to 28 V and an adjustable output voltage down to 0.9 V. It supports synchronous buck operation, achieving up to 95% efficiency. The device offers pin-selectable PWM/SKIP mode for optimized efficiency under light loads, separate standby control and overcurrent protection for each channel, and programmable short-circuit protection.
The TPS5120 is housed in a 30-pin TSSOP package. Its design incorporates features like low supply current (1 mA) and shutdown current (1 nA), a power good output, and high-speed error amplifiers. Sequencing is easily achieved by selecting appropriate soft-start capacitor values. The integrated 5-V linear regulator powers internal IC circuitry, simplifying the overall power supply design and reducing external component count.
