TPS51219. SLUSAG1B MARCH 2011 REVISED OCTOBER 2011. High Performance, Single-Synchronous Step-Down Controller with Differential Voltage Feedback 1 FEATURES DESCRIPTION.. 23 Differential Voltage Feedback The TPS51219 is a small-sized single buck controller with adaptive on-time control. It provides a choice of DC Compensation for Accurate Regulation control modes (D-CAP or D-CAP2 ) to meet a Wide Input Voltage Range: 3 V to 28 V wide range of system requirements. It is designed for Output Voltage Range: V to V with tight DC regulation requirements such as the VCCIO. Fixed Options of V and V application for Intel notebooks. The performance and flexibility of the TPS51219 makes it suitable for Wide Output Load Range: 0 A to 20 A+ low output voltage, high current, PC system power Adaptive On-Time Modulation with Selectable rails and similar point-of-load (POL) power supplies. Control Architecture and Frequency Differential voltage feedback and the voltage D-CAP Mode at 300 kHz/400 kHz for Fast compensation function combine to provide high Transient Response precision power to load devices.
