1 / 7 page SEMICONDUCTOR TECHNICAL DATA FC9961C 2019. 03. 14 1/7 Revision No : 0 Features Fast average current control Programmable constant off-time switching Linear dimming input PWM dimming input Output short circuit protection with skip mode Ambient operating temperature -40OC to +125OC Pin-compatible with the FC9910B Applications DC/DC or AC/DC LED driver applications LED backlight driver for LCD displays General purpose constant current source LED signage and displays Architectural and decorative LED lighting LED street lighting ► ► ► ► ► ► ► ► ► ► ► ► ► General Description The FC9961C is an average current mode control LED driver IC operating in a constant off-time mode. Unlike FC9910B, this control IC 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 ±3%. The IC is equipped with a current limit comparator for hiccup- mode output short circuit protection. The FC9961C can be powered from an 8.0 - 450V supply. A PWM dimming input is provided that accepts an external control TTL compatible signal. The output current can be programmed by an internal 265mV reference, or controlled externally through a 0 - 1.5V dimming input. FC9961C is pin-to-pin compatible with FC9910B and it can be used as a drop-in replacement for many applications to improve the LED current accuracy and regulation.
