Positive Logic On/Off signal, device code suffix “4”, turns the module ON during a logic High on the On/Off pin and turns the module OFF during a logic Low. For positive logic modules, the circuit configuration for using the On/Off pin is shown in Figure 28. The On/Off pin is an open collector/drain logic input signal (Von/Off) that is referenced to ground. During a logic-high (On/Off pin is pulled high internal to the module) when the transistor Q1 is in the Off state, the power module is ON. Maximum allowable leakage current of the transistor when Von/off = VIN,max is 10µA. Applying a logic-low when the transistor Q1 is turned-On, the power module is OFF. During this state VOn/Off must be less than 1.2V. When not using positive logic On/off pin, leave the pin unconnected or tie to VIN. VIN(+) Lynx II Module Q2 On/Off + Von/off Q1 R1 PWM Enable R3 Q3 - GND Css R4 Figure 28. Remote On/Off Implementation circuit. Remote Sense The Austin Lynx 24V power modules have a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage at the Remote Sense pin (See Figure 29). The voltage between the Sense pin and Vo pin must not exceed 0.5V. The amount of power delivered by the module is defined as the output voltage multiplied by the output current (Vo x Io). When using Remote Sense, the output voltage of the module can increase which increases the power output of the module. Make sure that the maximum output power of the module remains at or below the maximum rated power. When the Remote Sense feature is not being used, connect the Remote Sense pin to the output of the module.

Overcurrent Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting circuitry and can endure current limiting continuously. At the point of current-limit inception, the unit enters hiccup mode. The unit operates normally once the output current is brought back into its specified range. The average output current during hiccup is 20% IO, max. Input Undervoltage Lockout R2 Ion/off R d istribu tio n VO At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold. Overtemperature Protection To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will o shutdown if the overtemperature threshold of 130 C is exceeded at the thermal reference point Tref . The thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart. Output Voltage Programming The output voltage of the Austin Lynx 24V can be programmed to any voltage in the specified ranges by connecting a resistor (shown as Rtrim in Figure 30) between the Trim and GND pins of the module. Without an external resistor between the Trim and GND pins, the output of the module will be at the low-end of the specified range. To calculate the value of the trim resistor, Rtrim for a desired output voltage, use the following equations: 9 Austin LynxTM 24V: Non-isolated Power Modules: 20– 30Vdc input; 5.0 – 15.0Vdc Output; 70W Data Sheet March 31, 2008 Feature Descriptions (continued) Vo Rmargin-down Output Voltage Programming Austin Lynx or Lynx II Series ⎡ 10500 ⎤ Rtrim = ⎢ − 1000⎥ Ω ⎣Vo − 5.021 ⎦ Q2 Trim where, Rtrim is the external resistor in Ω and Vo is the desired output voltage Rmargin-up Rtrim V IN(+) V O(+) Q1 GND ON/OFF LOAD TRIM Rtrim Figure 31. Circuit Configuration for margining the output voltage. GND Figure 30. Circuit configuration to program output voltage using an external resistor. By using a ±0.5% tolerance trim resistor with a TC of ±100ppm, a set point tolerance of ±2% can be achieved as specified in the electrical specifications. The POL Programming Tool, available at www.lineagepower.com under the Design Tools section, helps determine the required external trim resistor needed for a specific output voltage. Voltage Margining Output voltage margining can be implemented in the Austin Lynx 24V modules by connecting a resistor, Rmargin-up, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargin-down, from the Trim pin to output pin for margining-down. Figure 31 shows the circuit configuration for output voltage margining. The POL Programming Tool, available at www.lineagepower.com under the Design Tools section, also calculates the values of Rmargin-up and Rmargin-down for a specific output voltage and % margin.

Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. The test set-up is shown in Figure 32. Note that the airflow is parallel to the long axis of the module as shown in figure 32.
