Краткое описание:
Synchronous Buck Controller for Precision Dimming LED Drivers
Дополнительная информация
The TPS92641 is a high-voltage, synchronous NFET controller for buck-current regulators. It uses valley current-mode operation with a controlled on-time architecture to maintain nearly constant switching frequency. It features a wide input voltage range from 7V to 85V and includes a dedicated shunt FET dimming MOSFET gate driver for high-resolution PWM dimming applications.
