TPS5124DBT Description

Short technical summary and product information.

The Texas Instruments TPS5124DBT is a dual-channel, independent, high-efficiency synchronous step-down PWM controller. It is designed 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, with adjustable output voltages 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, synchronous rectification, and a maximum duty cycle of 80%.

 

This device offers features such as Enable and Power Good signals, individual standby and soft-start for each channel, facilitating easy power sequencing. It also includes overvoltage and undervoltage protection, a built-in boot-strap diode, and a built-in 5V linear regulator. The operating temperature range is -40°C to 85°C.

 

The TPS5124DBT is available in a 30-TSSOP surface-mount package. Its design is suitable for applications including consumer game systems, DSP applications, digital set-top boxes, and VGA and sound cards.
