Product Overview:
The HV9971 is a primary-side control IC for driving a discontinuous conduction mode (DCM) flyback LED driver. The IC is optimized for operation at a constant full-load switching frequency of 100kHz and the universal input AC voltage range of 80-264VAC. It maintains 3% variation of the LED current setting, and features tight line and load regulation. The proprietary primary-side output current control employed in the HV9971 makes the output current setting insensitive to most component tolerances and parasitics without use of an opto-feedback.
