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 engineered for low-voltage, high-current power supply applications utilizing either a 5V or 12V bus voltage.

 

Key electrical specifications include an input voltage range of 4.5V to 15V and an adjustable output voltage from 0.9V to 12V. The controller supports a maximum output current of 20A and operates with a switching frequency up to 500kHz. It features voltage-mode PWM control, 180° out-of-phase operation, and individual standby and soft-start controls for each channel, facilitating easy power sequencing.

 

Additional features include high light-load efficiency, power good indication, synchronous rectification, overvoltage and undervoltage protection, a built-in boot-strap diode, and an integrated 5V linear regulator. The device also offers overcurrent detection with temperature compensation and an accurate ±1% reference voltage.

 

Packaged in a 30-TSSOP, the TPS5124DBTR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). This controller is well-suited for consumer game systems, DSP applications, digital set-top boxes, and VGA and sound cards.
