GM9130HV

High Power LED Driver

60V 3A LED Driver with Dimming Control

 

General Description

GM9130HV 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 GM9130HV

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 could 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 0V. The self-protection features include a cycle-by-cycle current limit and a thermal protection.

The GM9130HV is available in standard TO220-5, and TO263-5 packages.Besides, SOP8 with heat sink and TO252-5 packages are also available. However, these packages are limited to heat dissipation and the ILED is suggested below 2A.
