GM9130HV
3A LED Driver with Dimming Control
Description
Features
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.

Cycle by cycle current limit
The self-protection 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.

Application Notes
Output Current (ILED) Design, refer to Figure 1
The current through the LED’s can be set by the formula below.
ILED = VFB/RLOAD
For example, if 2Ω RLOAD is selected, with VFB = 200mV typical, then
ILED = 200 / 2 = 100mA
Power / Heat Consideration
Various ILED could be obtained by different resistor values as mentioned above. However, taking the
TO263-5 as an example, the maximum power rating must be followed.
TJ = PIC × θJA + TA
where PIC is the power of the IC itself, and θJA is the thermal resistance (junction to ambient). For
TO263-5, the θJA is 50°C/W, the safe power will be
PIC = TJ –TA /θJA = (150 – 25)/50 = 2.5W, and
PIC = PIN – PLED, Where
PIN = VIN × IIN, and
GM9130HVV2.02
PLED = VOUT × ILED (VOUT = VF × number of LED)
