Figure 3. External resistor configuration to increase the outputs Figure 4. External resistor configuration to increase the outputs 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.

AEO_ALO04/12/20/25x48 Series (Single Output 8th Brick) MODEL: AEO_ALO04/12/20/25x48 SERIES SHEET 8 OF 26 AUGUST 25, 2005 - REVISION G Basic Operation and Features (continued) 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 -V IN. 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. OUTPUT OVER VOLTAGE PROTECTION (OVP) The Over Voltage Protection circuit is non-latching - auto recovery mode. 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 62B 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 us ed in the circuit along with balanced bypass capacitors to shunt common mode currents into the ground plane. Shunting no ise 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 gr ound) connected to the converter output (-) terminal. Such a configuration is common practice to accommodate safety agency requirements. Gr ounding 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 measurem ent purposes, can be created by grounding the converter output (load) through a suitably sized inductor(s) while maintaining the necessary safety bonding.
