TPS56121DQPT Description

Short technical summary and product information.

The Texas Instruments TPS56121DQPT is a high-current synchronous buck converter from the SWIFT™ family. It is designed to provide efficient power conversion with an input voltage range of 4.5V to 14V and a maximum output current of 15A. The output voltage is adjustable, with a minimum configurable voltage of 0.6V.

 

Key electrical features include voltage mode control with feed-forward, adjustable current limit, and overcurrent protection. It supports prebiased startup and has a programmable soft-start feature. The device operates at selectable switching frequencies of 300 kHz, 500 kHz, and 950 kHz.

 

This converter is housed in a 22-pin 5mm x 6mm PQFN PowerPAD™ package, suitable for surface mounting. The operating temperature range is -40°C to 125°C (TJ). Features like Enable, Forced PWM, and Power Good signal enhance its utility in various power management applications.

 

It incorporates synchronous rectification for improved efficiency and utilizes R DS(on) sensing for both high-side and low-side MOSFETs. The device also includes UVLO (Under-Voltage Lockout) protection and thermal shutdown.
