HV9803 Dettagli del prodotto

General Description
The HV9803 is an open loop average-mode current control LED driver IC operating in a constant off-time mode. The IC features ±2% current accuracy, tight line and load regulation of the LED current without any need for loop compensation or high-side current sensing. Its auto-zero circuit cancels the effect of both the input offset voltage and the propagation delay in the current sense comparator.

Features
► Fast average current control
► Correction for propagation delay and offset voltage
► Fixed off-time switching mode
► Linear dimming input
► PWM dimming input
► Output short circuit protection with programmable skip mode
► Input under-voltage shutdown

Applications
► Backlighting of LCD Panels
