The TPS51020DBT from Texas Instruments is a multi-function dual-synchronous step-down controller primarily designed for notebook system power applications. It operates with a wide input voltage range from 4.5-V to 28-V and supports dual outputs, with an adjustable output voltage range from 0.9V to 24V.
This controller utilizes feed-forward voltage mode control for high efficiency and good line response, incorporating autoskip operation to maintain efficiency at light load conditions. It features an integrated 5-V, 60-mA regulator and a 0.85-V internal reference with 1% accuracy. The device also includes RDS(on) overcurrent detection and integrated OVP, UVP, and power good timers.
The TPS51020DBT is housed in a 30-pin TSSOP package, suitable for surface mount applications. Its design is optimized for high performance and high efficiency, making it a versatile solution for various switching applications, including DDR termination.
Key features include selectable dual and DDR modes, selectable fixed frequency voltage mode, and advanced power good logic that monitors both channels. It also offers a 180° phase shift between channels and integrated bootstrap diodes.
