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. 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 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.

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) 6 GM9130HV 3A LED Driver with Dimming Control Package Outline Dimensions – TO-263-5 0.176 - 0.184 (4.47 - 4.67) 0.046 - 0.054 (1.17 - 1.37) 0.389 - 0.408 (9.88 - 10.18) 0.061 - 0.069 (1.56 - 1.76) 0.322 - 0.339 (8.20 - 8.60) 0.028 - 0.036 (0.71 - 0.91) 0.596 - 0.612 (15.14 - 15.54) 3 7 0.200 - 0.216 (5.08 - 5.48) o 0-8 o 0.092 - 0.108 (2.34 - 2.74) 0.012 - 0.021 (0.31 - 0.53) 0.224 - 0.272 (5.70 - 6.90) 0.067 typ (1.70) Package Outline Dimensions – TO-220-5 0.048 - 0.052 (1.22 - 1.32) 0.400 + 0.015 0.400 - 0.005 (0.38 + 0.18) (0.38 - 0.03) 0.240 - 0.260 (6.10 - 6.60) 0.175 - 0.185 (4.45 - 4.75) 0.100 - 0.120 (2.54 - 3.05) 0.149 - 0.153 (3.78 - 3.89) 0.330 - 0.350 (8.38 - 8.89) 0.525 - 0.555 (13.34 - 14.10) 0.030 - 0.040 (0.76 - 1.02) 0.057 - 0.077 (1.45 - 1.96) 0.105 + 0.010 0.105 - 0.010 0.015 + 0.007 0.015 - 0.001 (2.67 + 0.25) (2.67 - 0.38) (0.38 + 0.18) (0.38 - 0.03) GM9130HVV2.02 0.525 - 0.555 (13.34 - 14.10) 7 GM9130HV 3A LED Driver with Dimming Control Package Outline Dimensions – TO252-5 0.250 – 0.262 (6.350 – 6.650) 0.087 – 0.094 (2.200 – 2.400) 0.205 – 0.213 (5.200 – 5.400) 0.017 – 0.023 (0.430 – 0.580) 0.374 – 0.390 (9.500 – 9.900) 0.150 REF (3.800) 0.213 – 0.224 (5.400 – 5.700) 0.000 – 0.005 (0.000 – 0.127) 0.100 – 0.114 (2.550 – 2.900) 0.050 TYP.
