Remote ON/OFF Function

APPLICATION NOTES

To lower the converter output voltage a resistor must

be placed between the Trim pin and -Vout pin as

shown in Figure 3.

Figure 4 – Remote ON/OFF Control Circuit

Protective Functions

Figure 3 – Trim Down Circuit

Temperature Shutdown

The resistance value required to achieve the desired

amount of positive/negative trim can be determined

by referring to the trim table for each model. If trim-

ming is not desired then the Trim pin may be left

open. In addition to the resistor values provided in

the trim tables, the following equations can be use

to calculate the required resistor value for a desired

output voltage. These equations apply for the 1.5V

and above models. For 1.2V models the trim tables

must be used.

The over temperature shutdown feature of the

SLC100 will cause the unit to shutdown at a typical

pwb internal monitor point temperature of 135^oC. This

protective feature is comprised of a thermistor in the

units control loop. At a temperature of 135^oC this

circuit will cause the PWM to go into an idle mode,

resulting in no output from the converter and prevent-

ing damage to the converter components. When the

temperature of the unit drops below 125^oC the fault

condition will clear and the converter will resume nor-

mal operation. If the cause of the over temperature

condition is not identiﬁed and corrected the unit will

continue to cycle on and off indeﬁnitely.

[

The nominal input voltage for the SLC100 is 48Vdc.

Once turned on reducing the input voltage to 32.0 Vdc

nominal will shut down the device. At an input voltage

less than 32.0V the under-voltage sensing circuit will

send a signal to the PWM causing it to go into idle

mode. This will result in no output from the converter,

protecting the unit from a high input current condition.

When the input voltage returns to a level above 33.3V

the unit will return to normal operation. The unit will

typically turn on at an input voltage of between 33.3V

and 34.5V nominal as indicated on the Product Data

Sheet. This is due to hysterisis designed into the

protective circuit to prevent excessive cycling of the

converter.

Remote ON/OFF Control Function

The SLC100 is equipped with a primary ON/OFF pin

used to remotely turn the converter on or off via a

system signal. The input is TTL open-collector and/or

FET open-drain compatible. For the positive logic

model a system logic low signal will turn the unit off.

For negative logic models a system logic high signal

will turn the converter off. For negative logic models

where no control signal will be used the ON/OFF pin

should be connected directly to –Vin to ensure proper

operation. For positive logic models where no control

signal will be used the ON/OFF pin should be left

open.
