TPS5124DBTR Description

Short technical summary and product information.

The TPS5124DBTR from Texas Instruments is a dual-channel, independent synchronous step-down PWM controller. It is suitable for low-voltage and high-current power supply applications, supporting input bus voltages of 5V or 12V. This controller features voltage-mode PWM control with a maximum switching frequency of 500 kHz.

Key electrical specifications include a maximum input voltage of 15V, a minimum input voltage of 4.5V, and a maximum output voltage of 12V. The minimum adjustable output voltage is 0.9V, and it supports a maximum output current of 20A. The device operates with a maximum duty cycle of 80% and a typical quiescent current of 0.0011A. It offers features such as individual standby and soft-start for each channel, enabling easy power sequencing.

The TPS5124DBTR is housed in a 30-pin TSSOP (DBT) package with an area of 49.92 mm². It includes overvoltage and undervoltage protection, a built-in boot-strap diode, and a built-in 5V linear regulator. The reference voltage is accurate to ±1% at 0.85V. Applications include consumer game systems, DSP applications, digital set-top boxes, and VGA and sound cards.

This controller is designed for high efficiency without requiring a current sense resistor, utilizing R DS(on) overcurrent detection with temperature compensation. It also provides synchronous rectification for improved efficiency.
