QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 518

SLIC POSITIVE INPUT TO NEGATIVE OUTPUT DC/DC CONVERTER

LTC3704

DESCRIPTION

Demonstration circuit 518 is a positive input to

negative output SLIC (Subscriber Line Interface

Circuit) converter featuring the LTC3704 switch-

ing controller. DC518 converts 4.5V to 15V input

to –24V and –70V output and provides over

200mA of output current from a 5V input. The

converter operates at 200kHz with high efficiency

of up to 92%. The DC518 is set to operate with

current sense resistor RS1 and input voltages up

to 15V. However, DC518 can be modified for No-

Rsense operation with a 5V input voltage, pro-

vided that MOSFET drain voltage does not exceed

36V (main output set between 0V and -24V). The

circuit features an optional soft-start circuit that can

be enabled or disabled with a single jumper.

DC518 has a jumper to program either continuous

or Burst-Mode operation and can be synchronized

to an external clock of up to 400kHz. Please refer

to the LTC3704 data sheet for design details and

applications information.

The DC518 can produce up to 200mA at both out-

puts from a 5V input source.

Design files for this circuit board are available.

Call the LTC factory.

QUICK START PROCEDURE

Demonstration circuit 518 is easy to set up to

evaluate the performance of the LTC3704. Refer to

Figure 1 for proper measurement equipment setup

and follow the procedure below:

NOTE:

When measuring the input or output volt-

age 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.

Place jumper JP1 in the Vin position. The “Pre

Reg” position is an optional bias source for appli-

cations modified for Vin higher than 36V. A bias

circuit including Q4 and D5 is installed on the

board in order to facilitate modifications for higher

Vin.

With power off, connect the input power supply to

Vin and GND. Make sure that the input power sup-

ply has sufficient current rating at minimum input

voltage for the required output load.

Turn on the power at the input.
