FP7182XR-G1

FP7182 LED Driver with Average-Mode Constant Current Control General Description The FP7182 is an average current mode control LED driver IC operating in a constant off-time mode. FP7182 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 compensation or high-side current sensing. The output LED current accuracy is ±2%. The FP7182 can be powered from an 8.0 - 100V supply. A PWM & Linear dimming input is provided that accepts an external control TTL compatible signal. The output current can be programmed by an internal 277mV reference. 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 Components for Operation  Internal 100V/1.5A 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 VIN GND DIM GND LED PWM and Linear Dimming VDD LX CS LX FP7182 This datasheet contains new product information.
