BW9130HV 3A LED Driver with Dimming Control
Description
BW9130HV is the monolithic IC designed for a step-down DC/DC converter capable of driving 3A load without an
additional transistor. The input voltage range is up to 60V. Its feedback voltage, VFB, is 200mV. The BW9130HV
operates at a switching frequency of 52kHz. The external shutdown function is controlled by a logic level on the
ON/OFF pin and then the circuit comes into the standby mode with ISTBY~50μA (typ.).
The ON/OFF pin may be used for the analog dimming. As the voltage on the ON/OFF pin is increased from 0.07V to
0.67V, the voltage on the FB pin falls from 200mV to 0. The self-protection features include a cycle-bicycles current
limit and a thermal protection. The BW9130HV is available in standard 5LTO220, and 5L-TO263 packages.
