GM9130HV - 3A LED Driver

Datasheet Summary

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.

Features

  • include a cycle-bycycle current limit and a thermal protection. The GM9130HV is available in standard TO2205, 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. Features ‹ ‹ ‹ ‹ ‹ ‹ ‹ Maximum input voltage up to 60V VFB: 200mV Frequency: 52KHz ILED = 3.0A maximum ON/OFF input may be used for the analog dimming Thermal protection Cycle by cycle current limit Typic.

GM9130HV 3A LED Driver with Dimming Control 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 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-bycycle current limit and a thermal protection.
