| GM7130HV 3A STEP DOWN VOLTAGE SWITCHING REGULATORS Description GM7130HV series is designed to provide all the active function for a step-down (buck) switching regulator, and drives a maximum load current as high as 3A line and load regulations. GM7130HV is available in fixed output voltages of 3.3V, 5V, 12V and a versatile Adjustable output version. These regulators are simple to use and require minimum number of external components. The features include internal frequency compensation and a fixed-frequency oscillator. The GM7130HV is high-efficiency replacements for popular three-terminal linear regulators, and is requiring a smaller heat sink or even no need heat sink. GM7130HV performs well with standard inductors from most of manufacturers, and simplifying the design of switch-mode power supplies. External shutdown is included with 80 A (typical) standby current. The output switch has cycle-by-cycle current limiting as well as thermal shutdown for full protection under fault conditions. Features 3.3V, 5V, 12V and Adjustable output versions Adjustable version output voltage range 1.23V to 57V VOUT accuracy is up to 2% under specified input voltage the output load conditions Input voltage range up to 60V Requires only 4 external components with High efficiency TTL shutdown capability, low power standby mode Built-in thermal shutdown, current limit protection Uses standard inductors 52 kHz fixed frequency internal oscillator GM7130HV operates at a switching frequency of 52 kHz which allowing smaller size filter components than what would be needed with lower frequency switching regulators. GM7130HV series are available in a standard 5lead TO-220, TO220B and TO263 packages.

Operating Ratings indicate conditions for which the device is intended to be functional but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. Note 2: All limits guaranteed at room temperature (standard type face) and at temperature extremes (bold type face). GM7130HVV2.00 6 Note 3: External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. When the GM7130HV is used as shown in the Figure 2 test circuit, system performance will be as shown in system parameters section of Electrical characteristics. Note 4: Output pin sourcing current. No diode, inductor or capacitor connected to output. Note 5: Feedback pin removed from output and connected to 0V. Note 6: Feedback pin removed from output and connected to +12V for the Adjustable, 3.3V, and 5V, versions, and +25V for the 12V and 15V versions, to force the output transistor OFF. Note 7: VIN =40V (60V for high voltage version). Note 8: The oscillator frequency reduces to approximately 11 kHz in the event of an output short or an overload which causes the regulated output voltage to drop approximately 40% from the nominal output voltage. This self protections feature lowers the average power dissipation of the IC by lowering the minimum duty cycle from 5% down to approximately GM7130HV 3A STEP DOWN VOLTAGE SWITCHING REGULATORS Test Circuit and Layout Guidelines Careful layout is important with any switching regulators. Rapidly switching currents associated with wiring inductance generate voltage transients which can cause problems. To minimize inductance and ground loops, the lengths of the leads indicated by heavy lines in Figure 1&2 below should be kept as short as possible. Single point grounding (as indicated or ground plane construction should be used for best results. When using the Adjustable version, place the programming resistors as close as possible to GM2576, to keep the sensitive feedback wiring short. 1 VIN VIN Unregulatedd DC Input CIN 100F 4 Feedback GM7130HV-x.x 3 GND 5 ON/OFF 2 Output L1 100H D1 D1 MBR360 COUT 1000F VOUT L O A D Preliminary Information Figure 1 Fixed Ouput Votlage Versions CIN = 100F, 75V, Aluminum Electrolytic COUT = 1000F, 25V, Aluminum Electrolytic D1 = Schottky, MBR360 L1 = 100H 1 VIN VIN Unregulatedd DC Input CIN 100F 3 GND 4 FB GM7130HV-ADJ 2 VOUT L1 100H R2 D1 MBR360 COUT 1000F VOUT 5.0V L O A D 5 ON/OFF R1 Figure 2 Adjustable Ouput Votlage Versions CIN = 100F, 75V, Aluminum Electrolytic COUT = 1000F, 25V, Aluminum Electrolytic D1 = Schottky L1 = 100H VOUT = VREF (1 + R2/R1) where VREF = 1.23V and R1 is between 1K to 5K GM7130HVV2.00 7 GM7130HV 3A STEP DOWN VOLTAGE SWITCHING REGULATORS Package Outline Dimensions - TO-263-5 0.389 - 0.408 (9.88 - 10.18) 0.061 - 0.069 (1.56 - 1.76) 0.176 - 0.184 (4.47 - 4.67) 0.046 - 0.054 (1.17 - 1.37) 0.322 - 0.339 (8.20 - 8.60) 0.028 - 0.036 (0.71 - 0.91) 0.596 - 0.612 (15.14 - 15.54) 7 3 0.200 - 0.216 (5.08 - 5.48) 0-8 0.224 - 0.272 (5.70 - 6.90) 0.067 typ (1.70) o o 0.092 - 0.108 (2.34 - 2.74) 0.012 - 0.021 (0.31 - 0.53) Package Outline Dimensions - TO-220-5 0.400 + 0.015 0.400 - 0.005 (0.38 + 0.18) (0.38 - 0.03) Preliminary Information 0.048 - 0.052 (1.22 - 1.32) 0.100 - 0.120 (2.54 - 3.05) 0.149 - 0.153 (3.78 - 3.89) 0.525 - 0.555 (13.34 - 14.10) 0.175 - 0.185 (4.45 - 4.75) 0.240 - 0.260 (6.10 - 6.60) 0.330 - 0.350 (8.38 - 8.89) GM7130HVV2.00 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 (2.67 + 0.25) (2.67 - 0.38) 0.015 + 0.007 0.015 - 0.001 (0.38 + 0.18) (0.38 - 0.03) 8 GM7130HV 3A STEP DOWN VOLTAGE SWITCHING REGULATORS Ordering Number GM 7130HV A APM Gamma Micro Circuit Type Output Voltage A: Adj 3.3 = 3.3V 5.0 = 5.0V 12 = 12.0V TA5 Package Type TA5: TO263-5 TB5: TO-220-5 TB5B: TO-220B-5 R Shipping Type R:Taping & Reel T:Tube G Blank: Pb-free G: Green Preliminary Information 8 10 6 GM7130HVV2.00 9 |
