3A STEP-DOWN VOLTAGE SWITCHING REGULATORS
Features
Description
GM7130 of regulators provides all the active
functions for a step- down (buck) switching
regulator, and drives 3A load with excellent
line and load regulation. GM7130 is available
in fixed output voltages of 3.3V, 5V, 12V
15V , and a versatile Adjustable output
version. These regulators are simple to use
and require a minimum number of external
components. Features include internal frequency compensation and a fixed-frequency
oscillator.
The GM7130 is high-efficiency replacements
for popular three-terminal linear regulators,
and is requiring a smaller heatsink or even
no heatsink.
3.3V, 5V, 12V, 15V, Adjustable output versions
GM7130 performs well with standard
inductors from several manufacturers, and
simplifying the design of switch-mode
power supplies. GM7130 guarantees ±4%
tolerance on output voltage within specified
input voltages and output load conditions,
and ±10% on the oscillator frequency.
External shutdown is induced with 50 uA
(typical) standby current. The output switch
has cycle-by-cycle current limiting as well
as thermal shutdown for full protection under
fault conditions.
52 kHz fixed frequency internal oscillator
Adjustable version output voltage range 1.23V
to 37V ±4% max over line and load conditions
3A output current
Input voltage range 7V to 40V
Requires only 4 external components
High efficiency
TTL shutdown capability, low power standby
mode
Thermal shutdown, current limit protection

ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Operating Ratings indicate conditions for which the device is intended to be functional, but do not
guarantee specific performance limits. Guaranteed specifications and Test conditions are shown in
Electrical Characteristics.
Note 2: All limits guaranteed at 25°C (standard type face) and over full operating temperature range (bold
type face). All 25°C limits are 100% production tested. All limits over full operating temperature
range are guaranteed via correlation using standard Statistica Quality Control methods.
Note 3: External components such as the catch diode, inductor, input and output capacitors can affect
switching regulator system performance. When the GM7130 is used as shown in the Figure 1 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
Note 8: Junction to ambient thermal resistance (no external heat sink) for the 5 lead TO-220 package
mounted vertically, with ½ inch leads in a socket, or on a PC board with minimum copper area.
Note 9: Junction to ambient thermal resistance (no external heat sink) for the 5 lead TO-220 package
mounted vertically, with ¼ inch leads soldered to a PC board containing approximately 4 square
inches of copper area surrounding the leads.
Note 10: If the TO-263 package is used, the thermal resistance can be reduced by increasing the PC board
Copper area thermally connected to the package. Using 0.5 square inches of copper area, qJA is
50°C//W, with 1 square inch of copper area, qJA is 37°C/W, and with 1.6 or more square inches of
copper area, qJA is 32°C/W.
GM7130
Note 11: 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- protection feature lowers the Average power dissipation of GM7130
by lowering the minimum duty cycle from 5% down to approximately 2%.

TEST CIRCUIT AND LAYOUT GUIDELINES
Careful layout is important with any switching regulator. 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 below should be kept as short as possible. Singlepoint grounding (as indicated in Figure 1) or ground plane construction should be used for best results. When
using the Adjustable version, place the programming resistors as close as possible to Gm7130, to keep the
sensitive feedback wiring short.
