DEMO CIRCUIT 1316

QUICK START

LT1913

GUIDE

LT1913EMSE

3.5A,25V Step-down Switching Regula-

tor with SYNC Function

DESCRIPTION

Demonstration circuit 1316 is a monolithic step-

down DC/DC switching regulator featuring LT1913.

The LT1913 can be synchronized over a 250 KHz

to 2 MHz range. The demo board is designed for

5V output from a 6.5V to 25V input. The wide input

range of the LT1913 allows a variety of input

sources. The typical sources are automotive bat-

teries, wall adaptors and industrial supplies.

An optional EMC filter at the input is provided on

the bottom of the board, which greatly reduces the

conductive EMI noise at the input side. Customers

can use this optional circuit by cutting the input

trace on the bottom of the board and install the

components. The current mode control scheme

creates fast transient response and good loop sta-

bility. The gate drive of the internal switch is

boosted to a voltage that is higher than the Vin to

ensure saturation of the switch. The LT1913’s inte-

grated boost diode reduces the parts count. The

RUN/SS pin can be used to set the part in micro-

power shutdown mode, reducing the supply cur-

rent to less than 1uA. The RUN/SS pin can also be

used to program soft start. In this mode, the

RUN/SS pin is driven through an external RC filter

to create a voltage ramp on this pin. The soft start

function reduces the input current surge during

start-up.

The LT1913 datasheet gives a complete descrip-

tion of the part, operation and application informa-

tion. The datasheet must be read in conjunction

with this quick start guide for demo circuit 1316.

Note: It is best to ground the SYNC pin if the

SYNC function is not being used.

Design files for this circuit board are available.

QUICK START PROCEDURE

Demonstration circuit 1316 is easy to set up to

evaluate the performance of the LT1913. Refer to

Figure 1 for proper measurement equipment setup

and follow the procedure below:

NOTE.

When measuring the input or output voltage ripple, care

must be taken to avoid a long ground lead on the oscilloscope

probe. Measure the input or output voltage ripple by touching the

probe tip directly across the Vin or Vout and GND terminals. See

Figure 2 for proper scope probe technique.
