TPS51219 – 51219 – QFN- 16 - Texas Instruments

High Performance , Single-Synchronous Step-Down Controller with Differential Voltage Feedback

تنها سنکرون کنترل کننده گام به پایین با فیدبک ولتاژ دیفرانسیل

 

DESCRIPTION

 

The TPS51219 is a small-sized single buck controller with adaptive on-time control. It provides a choice of control modes (D-CAP™ or D-CAP2™) to meet a wide range of system requirements. It is designed for tight DC regulation requirements such as the VCCIO application for Intel® notebooks. The performance and flexibility of the TPS51219 makes it suitable for low output voltage, high current, PC system power

rails and similar point-of-load (POL) power supplies Differential voltage feedback and the voltage compensation function combine to provide high precision power to load devices A small package, fixed voltage options and minimal external component count saves cost and space while a dedicated EN pin and pre-set frequency selections minimize design effort. The skip-mode at light load condition, strong gate drivers, and low-side FET RDS(on) current sensing provides high efficiency .operation over a broad load range. The external resistor current sense option enables accurate  current sensing. The conversion input voltage (the high-side FET drain voltage) ranges from 3 V to 28 V and output voltage ranges from 0.5 V to 2.0 V. The device requires an external 5-V supply .The TPS51219 is available in a 16-pin, QFN package and is specified for ambient temperature from -40°C to 85°C
