TPS51020DBTR Description

Short technical summary and product information.

The Texas Instruments TPS51020DBTR is a multi-function, dual-synchronous step-down controller specifically designed for high-performance, high-efficiency notebook system power applications. It utilizes feed-forward voltage mode control for excellent line response and incorporates autoskip operation to maintain high efficiency at light load conditions.

 

Key electrical specifications include a wide input voltage range of 4.5-V to 28-V and selectable output voltages from 0.9V to 24V. The device features an integrated 5-V, 60-mA regulator and a 1% internal 0.85-V reference. Overcurrent detection is implemented using RDS(on) sensing. The controller supports selectable dual and DDR modes, fixed frequency voltage mode, and advanced power good logic monitoring both channels.

 

Packaged in a 30-pin TSSOP, the TPS51020DBTR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. The controller is designed for applications such as notebook computers, system bus and I/O power, and DDR I or DDR II termination.
