TPS56121DQPR Description

Short technical summary and product information.

The Texas Instruments TPS56121DQPR is a synchronous SWIFT™ buck converter designed for high-current applications. It features a wide input voltage range from 4.5V to 14V and supports an output current of up to 15A.

 

This converter utilizes voltage mode control with feed-forward and incorporates features such as adjustable current limit, enable, forced PWM, overcurrent protection, and power good indication. It supports prebias startup and has a programmable soft-start function. The device operates with a fixed switching frequency option of 300 kHz, 500 kHz, or 950 kHz.

 

The TPS56121DQPR is housed in a 22-pin 5mm x 6mm PQFN PowerPAD™ package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). The integrated high-side and low-side MOSFETs use R DS(on) sensing for efficiency.

 

Key electrical specifications include a 600mV reference voltage with 1% accuracy and a maximum duty cycle of 93%. The quiescent current (Iq) is typically 0.0025A.
