The HV9910CLG-G is an universal high brightness open loop current mode control LED Driver IC can be programmed to operate in either a constant frequency or constant OFF-time mode. It includes a 15 to 450V linear regulator which allows it to work from a wide range of input voltages without the need for an external low voltage supply. It includes a TTL compatible PWM dimming input that can accept an external control signal with a duty ratio of 0 to 100% and a frequency of up to a few kHz. It also includes a 0 to 250mV linear dimming input which can be used for linear dimming of the LED current. It is equipped with built-in thermal-shutdown protection. Since the HV9910C operates in open loop current mode control, the controller achieves good output current regulation without the need for any loop compensation. Also, being an open loop controller, PWM dimming response is limited only by the rate of rise of the inductor current, enabling a very fast rise and fall times of the LED current.
● Switch mode controller for single switch LED drivers
● Open loop peak current controller
● Constant frequency or constant OFF-time operation
● Linear and PWM dimming capability
● Requires few external components for operation
● Over-temperature protection
