TPS51123RGER Description

Short technical summary and product information.

The Texas Instruments TPS51123RGER is a dual-channel synchronous buck controller designed for efficient power management. It operates with an input voltage range from 4.5V to 28V and provides up to four outputs, combining step-down buck synchronous controllers with linear LDO regulators.

 

Key electrical specifications include a typical quiescent current of 0.00055A and a maximum duty cycle of 93%. The device features adaptive on-time control architecture with selectable frequency settings, operating at 460kHz. It also includes R DS(on) current sensing with a temperature coefficient of 4500 ppm/°C.

 

This controller is housed in a 24-VQFN (4x4 mm) package, suitable for surface mount applications. The operating temperature range is -40°C to 85°C. The TPS51123RGER is designed for applications requiring flexible and efficient power conversion.

 

Environmental compliance includes RoHS3 compliance, Moisture Sensitivity Level 1, and REACH unaffected status, though these require verification.
