HV9910C is an enhanced drop-in replacement to the HV9910B, designed to convert high voltage supplies (85-265VAC rectified) or (15-450VDC) to a constant current source for powering a string or a combination of strings of high brightness LEDs. It can be programmed to operate in either a constant frequency or constant off-time mode and includes a 15-450V linear regulator that allows it to work from a wide range of input voltages without the need for an external low voltage supply, detailed the company.
HV9910C is available in a lead(Pb)-free/RoHS compliant 8L SOICN and 16L SOICN package (HV9910CLG-G and HV9910CNG-G, respectively). Samples are available from stock.
