Краткое описание:
65V, 2A Buck LED Driver with Analog or PWM Dimming
Дополнительная информация
The TPS922051 is a 2A non-synchronous buck LED driver with a wide input range of 4.5V to 65V. It integrates a 300mΩ low-side NMOS FET and is designed for high power density and high efficiency LED driving. The device supports both fast PWM dimming with pulse widths as narrow as 50ns and analog dimming with a 200:1 ratio. It features adaptive off-time current mode control and includes comprehensive protection such as thermal shutdown, cycle-by-cycle current limiting, and LED open/short detection.
