Product Summary

The TPS53124RGER is a dual, Adaptive on-time DCAP mode synchronous controller. The part enables system designers to cost effectively complete the suite of digital TV power bus regulators with the absolute lowest external component count and lowest standby consumption. The main control loop for the TPS53124RGER uses the D-CAP mode that optimized for low ESR output capacitors such as POSCAP or SP-CAP promises fast transient response with no external compensation. The part provides a convenient and efficient operation with conversion voltage from 4.5V to 24V and output voltage from 0.76V to 5.5V. The applications of the TPS53124RGER include Digital TV Power Supply, Networking Home Terminal, and Digital STB.
