DEMO MANUAL DC1198B-B

 QUICK START PROCEDURE

Demonstration circuit DC1198B-B provides a simple way 
to evaluate the performance of the LTM4607EV. Please 
refer to Figure 1 for the proper measurement equipment 
set-up, and follow the procedure below: 

1.  Place jumpers in the following positions for a typical 

12V

OUT

 application:

RUN

CLOCK

MODE

START

On

Prog

CCM

SSO

2.   With the power off, preset the load to 0A and the V

IN

 

supply to less than 36V. Next, connect the input power 
supply, load and meters, as shown in Figure 1. 

3.   Turn on the power at the input. The output voltage 

should be 12V, ±2%.

4.   Once the proper output voltage is established, adjust 

the load within the operating range and observe the 
output voltage regulation, ripple voltage, effi ciency 
and other parameters. The cooling fan and lower cur-
rent sensing resistor are necessary for V

IN

 < 6V and 

I

OUT

 = 5A.

5.   To measure the input and output ripple, please refer 

to Figure 2 for the proper set-up.

6.   The voltage at PLLFLTR determines the switching 

frequency. Modify R6 and R7 to adjust the switching 
frequency. Do not allow the voltage at pin PLLFLTR 
to exceed 2.4V.

7.   Inductor and R

SENSE

 should be modifi ed to accom-

modate certain input and output conditions. Please 
refer to Table 1 for recommended inductors.
