L6728DTR Description

Short technical summary and product information.

The L6728DTR is a step-down (buck) DC-DC switching controller from STMicroelectronics designed for compact power management solutions. It operates from a 5 V to 12 V supply and delivers a positive transistor driver output with 0.8% output voltage accuracy. The controller supports a maximum duty cycle of 80% and features synchronous rectifier operation for improved efficiency. Switching frequency is configurable between 300 kHz and 600 kHz.

 

Control features include enable, phase control, and power good indication, making it suitable for sequenced power rails. The device does not support clock synchronization. It provides a single output with one phase. Internal reference voltage is set at 0.8 V.

 

The L6728DTR is housed in a 10-VFDFN exposed pad package (10-DFN 3x3 mm) for surface mount assembly. It is rated for a junction temperature range of -40°C to 125°C, supporting industrial and extended temperature environments.
