Likewise, it has also been programmed to turn-off when VIN drops down to 31-34 VDC. OUTPUT VOLTAGE ADJUST/TRIM The converter comes with a TRIM pin (PIN 6), which is used to adjust the output by as much as 90% to 110% of its set point. This is achieved by connecting an external resistor as described below. To INCREASE the output, external Radj_up resistor should be connected between TRIM PIN (Pin6) and +SENSE PIN (Pin 7). Please refer to Equation (1) for the required external resistance and output adjust relationship. Equation (1a): 1.5V to 12V Radj_up =   5.1 × Voset × (100 + ∆%) 510  − − 10.2  ∆% 1.225× ∆%    5.1 × Voset × (100 + ∆%)   0.6 × ∆% ΚΩ Equation (1b): 1.2V Radj_up = − 510 ∆% − 10.2  Figure 3.

External resistor configuration to decrease the o/p. Where: ∆% = percent change in output voltage OUTPUT ENABLE The converter comes with an Enable pin (PIN 2), which is primarily used to turn ON/OFF the converter. Both a Positive (no “N” suffix required) and a Negative (suffix “N” required) Enable Logic options are being offered. Please refer to Table 2 for the Part Numbering Scheme. For Positive Enable, the converter is turned on when the Enable pin is at logic HIGH or left open. The unit turns off when the Enable pin is at logic LOW or directly connected to -VIN. On the other hand, the Negative Enable version turns unit on when the Enable pin is at logic LOW or directly connected to -VIN. The unit turns off when the Enable pin is at Logic HIGH.

The output of the converter is terminated under an OVP fault condition (Vo > OVP threshold). The converter will attempt to restart until the fault is removed. There is a 100ms lockout period between restart attempts. OVER CURRENT PROTECTION (OCP) The Over Current Protection is non-latching - auto recovery mode. The converter shuts down once the output current reaches the OCP range. The converter will attempt to restart until the fault is removed. There is a 100ms lockout period between restart attempts. OVER TEMPERATURE PROTECTION (OTP) The Over Temperature Protection circuit will shutdown the converter once the average PCB temperature (See Figure 90B for OTP reference sense point) reaches the OTP range. This feature prevents the unit from overheating and consequently going into thermal runaway, which may further damage the converter and the end system. Such overheating may be an effect of operation outside the given power thermal derating conditions. Restart is possible once the temperature of the sensed location drops to less than 110°C. REMOTE SENSE The remote sense pins can be used to compensate for any voltage drops (per indicated max limits) that may occur along the connection between the output pins to the load. Pin 7 (+Sense) and Pin 5 (-Sense) should be connected to Pin 8 (+Vout) and Pin 4 (Return) respectively at the point where regulation is desired. The combination of remote sense and trim adjust cannot exceed 110% of VO. When output voltage is trimmed up (through remote sensing and/or trim pin), output current must be derated and maximum output power must not be exceeded.

Two common mode connected inductors are used in the circuit along with balanced bypass capacitors to shunt common mode currents into the ground plane. Shunting noise current back to the converter reduces the amount of energy reaching the input LISN for measurement. The application circuit shown has an earth ground (frame ground) connected to the converter output (-) terminal. Such a configuration is common practice to accommodate safety agency requirements. Grounding an output terminal results in much higher conducted emissions as measured at the input LISN because a hard path for common mode current back to the LISN is created by the frame ground. “Floating” loads generally result in much lower measured emissions. The electrical equivalent of a floating load, for EMI measurement purposes, can be created by grounding the converter output (load) through a suitably sized inductor(s) while maintaining the necessary safety bonding.

When wave soldering, the converter pins should be preheated for 20-30 sec at 110°C and wave soldered at 260°C for less than 10 sec. When hand soldering, the iron temperature should be maintained at 425°C and applied to the converter pins for less than 5 seconds. Longer exposure can cause internal damage to the converter. Cleaning can be performed with cleaning solvent IPA or with water. For SMT terminated modules, refer to Figure 92 for the recommended reflow profile. 183°C PEAK TEMPERATURE 200°C - 230°C 180 160 140 120 100 80 60 40 20 0 0 30 60 90 120 150 180 210 240 270 300 REFLOW ZONE 110°C < 80 sec PRE-HEAT ZONE 120 - 180 sec SLOPE < 4°C /sec TIME (seconds) Figure 92.
