| 产品特性 |
【产品特性】 * Support NVIDIA Open VReg Type-2+ PWMVID Technology* Wide Input Voltage Range 3V ~ 20V * Robust Constant On-Time Control *2/1 Phase Operation * Two Integrated MOSFET Drivers with Shoot-Through Protection and Internal Bootstrap Schottky Diode * Selectable Soft-Start * Multi-Function Pin (FS/OC) for Linear OCPThreshold Setting and Switching FrequencySelection * External Compensation * Dynamic Output Voltage Adjustment * Power Good Indication * Over Voltage Protection * Under Voltage Protection * Over Temperature Protection * RoHS Compliant and Halogen Free The uP1666Q adopts proprietary RCOT TM technology, providing flexible selection of output LC filter and excellent transient response to load and line change. The uP1666Q supports NVIDIA Open Voltage Regulator 2+ with PWMVID feature. The PWMVID input is buffered and filtered to generate accurate reference voltage, and the output voltage is precisely regulated to the reference input. The uP1666Q uses MOSFET RDS(ON) current sensing for channel current balance. The uP1666Q also implements a multi-function pin (FS/OC) for switching frequency selection and OCP threshold setting. |
