Краткое описание:
7V to 85V Synchronous Buck Controller for Precision Dimming LED Drivers
Дополнительная информация
The TPS92640 is a high-voltage, synchronous NFET controller designed for buck current regulators. It utilizes a controlled on-time architecture for valley current-mode operation, which simplifies loop compensation and maintains a nearly constant switching frequency. The device supports a wide input voltage range from 7V to 85V and is engineered for high-speed PWM dimming and analog dimming applications.
