QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 545

MICROPOWER STEP-UP SWITCHING REGULATOR IN SC-70

LT3460ESC6

DESCRIPTION

Demonstration circuit 545 features the LT3460, step-up

DC/DC converter with 1.3MHz constant frequency in a SC70

package. There are two switching regulator circuits in

DC545. The 12V output boost converter (upper circuit) is de-

signed to convert 5V input to 12V output at 70mA of load

current and the SEPIC converter (lower circuit) is designed to

convert 10V ~ 16V input to 12V at 50mA.

Each circuit has a jumper for testing SHDN mode operation.

Placing the jumper (JP1 & JP2) to “Hi” enables LT3460 op-

eration and placing the jumper to “Lo” disables the LT3460

and the converter will turn off.

Design files for this circuit board are available. Call the LTC

factory.

QUICK START PROCEDURE

12V OUTPUT BOOST CONVERTER (UPPER CIRCUIT)

Refer to Figure 1 for proper measurement equipment setup and follow the procedure below:

1. Connect the input power supply (set at 5V) to

Vin

and

GND

pins of the

boost converter

2. Turn on the input power supply and observe the

output voltage, the output voltage should read

≅

12V

3. Turn on the load preset at

70mA

. The input cur-

rent should read around

≅

200mA and the output

voltage should be 12.1V

0.25V.

4. Check the output ripple using the oscilloscope (re-

fer to Figure 3). The output ripple should not be

greater than 60mV. Also check the switching fre-

quency, it should be

≅

1.3MHz.

12V OUTPUT SEPIC CONVERTER (LOWER CIRCUIT)

Refer to Figure 2 for proper measurement equipment setup and follow the procedure below:

1. Connect the input power supply (set at 10V) to the

Vin

and

GND

pins of the

SEPIC

converter

2. Turn on the input power supply. The output volt-

ages should read 0V.

3. Turn on the load box preset at 50mA. The input

current should read around

≅

75mA and the out-

put voltage should now read 12.1V

0.20V.

4. Slowly change the input power supply voltage

from 10V to 16V while observing the output volt-

age. The output should stay within 12.1V

0.20V.

5. Observe the input current at 16V, it should read

around 50mA.

6. Change the input power supply back to 10V and

check the output ripple using the oscilloscope (re-

fer to Figure 3). The output ripple should not be

greater than 60mV. Also check the switching fre-

quency, it should be

≅

1.3MHz.
