HV9910BDB3, Demo Board is a high current LED driver designed to drive one LED or two LEDs in series at currents up to 1A from a 10 - 30VDC input with constant frequency mode. The demo board uses HV9910B Universal LED driver IC to drive a buck converter. The HV9910BDB3 can be configured to operate in either a constant frequency mode (for driving a single LED) or in a constant off-time mode (for driving two LEDs)
