HV9961, LED driver with constant current control in average current mode Description The HV9961 is an LED driver IC with constant current control in average current mode, operating in a constant off-time mode. Unlike the HV9910B, this control IC does not generate a peak-to-average error. This greatly improves the accuracy, line and load control of the LED current without the need for loop compensation or high-side current measurement. The accuracy of the LED output current is ±3%. The IC is equipped with a current limiting comparator for short-circuit protection of the output in Hiccup mode. The HV9961 can be operated with a supply voltage of 8V-450V. It has a PWM DIMM input that accepts an external TTL-compatible control signal. In addition, the output current can be programmed via an internal 275 mV reference or controlled externally via a linear dimming input of 0V-1.5V. The HV9961 is pin-to-pin compatible with the HV9910B. https://elecena.pl/product/19732807/hv9961ng-g-m934-led-driver-with-constant-current-control-linear-taped-so-16 2021-10-27 https://elecena.pl/product/19732807/hv9961ng-g-m934-led-driver-with-constant-current-control-linear-taped-so-16 2022-10-20 https://elecena.pl/product/19732807/hv9961ng-g-m934-led-driver-with-constant-current-control-linear-taped-so-16 2023-07-08 https://elecena.pl/product/19732807/hv9961ng-g-m934-led-driver-with-constant-current-control-linear-taped-so-16 2024-07-14 https://elecena.pl/product/19732807/hv9961ng-g-m934-led-driver-with-constant-current-control-linear-taped-so-16 2025-02-04 https://elecena.pl/product/19732807/hv9961ng-g-m934-led-driver-with-constant-current-control-linear-taped-so-16 2025-12-14
