TPS53124 用于低压电源轨的双路同步降压控制器,频率为 380kHz

TPS53124 描述

The TPS53124 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 TPS53124 uses the D-CAPTM 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 voltages from 4.5 V to 24 V and output voltage from 0.76 V to 5.5 V.

The TPS53124 is available in the 24-pin RGE package and in the 28-pin PW package and is specified from -40°C to 85°C ambient temperature range.
