TPS92642-Q1 Infrared LED Driver Texas Instruments TPS92642-Q1 Infrared LED Driver is a monolithic, synchronous bus LED driver operating at a 5.5V to 36V input voltage range. The adaptive on-time control with a near-constant switching frequency can be set between 100kHz and 2.2MHz for this device. The TPS92642-Q1 high-performance LED driver can independently modulate LED current using analog or PWM dimming techniques. This driver incorporates an internal pulse monitoring circuit that limits the maximum pulse duty cycle. This TPS92642-Q1 device is AEC-Q100 qualified for automotive applications. The TPS92642-Q1 LED driver is used in Driver Monitoring Systems (DMS), IR LED, and laser driver applications.
