FP7122 Datasheet | Feeling Technology

Description The FP7122 is an average current mode control LED driver IC operating in a constant off-time mode. FP7122 does not produce a peak-to-average error, and therefore greatly improves accuracy, line and load regulation of the LED current without any need for loop pensation or high-side current sensing. The output LED current accuracy is ±3%. The FP7122 can be powered from an 8.0 - 100V supply. A PWM & linear dimming input is provided that accepts an external control TTL patible signal. The output current can be programmed by an internal 250m V reference. or controlled externally through a 0.2 - 1.5V dimming input. Features - Fast Average Current Control - Internal 8 to 100V Linear Regulator - Linear and PWM Dimming Capability - Output Short Circuit Protection with Skip Mode - Requires Few External ponents for Operation - Internal 100V/6A N-MOSFET Applications - DC/DC or AC/DC LED Driver Applications - Back Lighting of Flat Panel Displays - General Purpose Constant Current Source - Signage and Decorative LED Lighting - Chargers Typical Application Circuit VIN Up to 100V PWM and Linear Dimming VIN DIM VDD GND GND This datasheet contains new product information.
