5 Remote Sense

This function is used to compensate for voltage drops on Rw. The Sense(+), Sense(-), Vout(+), and Vout(-)terminals should meet the following requirements:

[Vout(+) – Vout(-)] – [Sense(+) – Sense(-)] ≤ 10% x Vnom

(Vnom is the rated output voltage.)

Figure 5-1 Configuration diagram for remote sense

NOTE

1. Rw indicates the line impedance between the output terminal and the load.

2. If the remote sense function is disabled, the Sense(+) terminal directly connects to the Vout(+) terminal and the Sense(-)terminal directly connects to the Vout(-) terminal.

6 Protection Characteristic

l Input Undervoltage ProtectionThe converter will shut down after the input voltage drops below the undervoltage protection threshold forshutdown. The converter will start to work again after the input voltage reaches the input undervoltageprotection threshold for startup. For the hysteresis, see Table 2-5.

l Output Overvoltage ProtectionThe converter equipped with current limiting circuitry can provide protection from an output overload orshort circuit condition. If the output current exceeds the output overcurrent protection threshold, theconverter enters hiccup mode. When the fault condition is removed, the converter will automatically restart,see Table 2-6.

l Output Overcurrent ProtectionWhen the voltage directly across the output pins exceeds the output overvoltage protection threshold, theconverter will enter hiccup mode. When the fault condition is removed, the converter will automaticallyrestart.

l Overtemperature ProtectionA temperature sensor on the converter senses the average temperature of the module. It protects the converterfrom being damaged at high temperatures. When the temperature exceeds the overtemperature protectionthreshold, the output will shut down. It will allow the converter to turn on again when the temperature of thesensed location falls by the value of Overtemperature Protection Hysteresis.

8.5 Thermal Consideration

Thermal Test Point

Decide proper airflow to be provided by measuring the temperature of the PCB near the thermal resistor shown inFigure 23 to protect the converter against overtemperature. The overtemperature protection threshold is alsoobtained based on this thermal test point.

Figure 8-2 Thermal test point

Power Dissipation

The converter power dissipation is calculated based on efficiency. The following formula reflects the relationshipbetween the consumed power (Pd), efficiency (ŋ), and output power (Po): Pd = Po(1-ŋ)/ŋ.

8.6 MSL RatingStore and transport the converter as required by the MSL rating 1 specified in the J-STD-020D/033C. The surfaceof a soldered converter must be clean and dry. Otherwise the assembly, test, or even reliability of the converterswill be negatively affected.

8.7 Mechanical Consideration

InstallationAlthough the converter can be mounted in any direction, free airflow must be available.

SolderingThe converter supports standard wave soldering and hand soldering. Reflow soldering is not allowed.

1. For wave soldering, the converter pins can be soldered at 260°C for less than 7 seconds.2. For reflow soldering, the converter pins can be soldered at 250°C for less than 10 seconds.3. For hand soldering, the iron temperature should be maintained at 350°C to 420°C and applied to the

converter pins for less than 10 seconds.

The converter can be rinsed using the isopropyl alcohol (IPA) solvent or other suitable solvents.
