Function Specifications

Enable (ON/OFF) Control (Pin 3 and Pin4):

 The Enable pin allows the power module to be switched on and off electronically. The Enable (On/Off) function is useful for conserving battery power, for pulsed power application or for power up sequencing.

 The Enable pin is referenced to the -Vin. It is pulled up internally, so no external voltage source is required. An open collector (or open drain) switch is recommended for the control of the Enable pin.

 When using the Enable pin, make sure that the reference is really the -Vin pin, not ahead of EMI filtering or remotely from the unit. Optically coupling the control signal and locating the opto coupler directly at the module will avoid any of these problems. If the Enable pin is not used, it can be left floating (positive logic) or connected to the -Vin pin (negative logic).Figure A details five possible circuits for driving the ON/OFF pin. Figure B is a detailed look of the internal ON/OFF circuitry.

Remote Sensing (Pins 7 and 8):

Remote sensing allows the converter to sense the output voltage directly at the point of load and thus automatically compensates the load conductor distribution & contact losses (Figure C). There is one sense lead for each output terminal, designated +Sense and -Sense. These leads carry very low current compared with the load leads. Internally a resistor is connected between sense terminal and power output terminal. If the remote sense is not used, the sense leads needs to be shorted to their respective output leads(Figure D).

 

Care has to be taken when making output connections. If the output terminals should disconnect before the sense lines, the full load current will flow down the sense lines and damage the internal sensing resistors. Be sure to always power down the converter before making any output connections. The maximum compensation voltage for line drop is up to 0.5V

Protection Features

·Input Under-Voltage Lockout: The converter is designed to turn off when the input voltage is too low, helping avoid an input system instability problem, The lockout circuitry is a comparator with DC hysteresis. When the input voltage is rising, it must exceed the typical Turn-On Voltage Threshold value(listed on the specification page) before the converter will turn on. Once the converter is on, the input voltage must fall below the typical Turn-Off Voltage Threshold value before the converter will turn off.

·Output Current Limit: The maximum current limit remains constant as the output voltage drops. However, once the impedance of the short across the output is small enough to make the output voltage drop below the specified Output DC Current-Limit Shutdown Voltage, the converter into hiccup mode indefinite short circuit protection state until the short circuit condition is removed. This prevents excessive heating of the converter or the load board.

·Over-Temperature Shutdown: A temperature sensor on the converter senses the average temperature of the module. The thermal shutdown circuit is designed to turn the converter off when the temperature at the sensed location reaches the Over-Temperature Shutdown value. It will allow the converter to turn on again when the temperature of the sensed location falls by the amount of the Over-Temperature Shutdown Restart Hysteresis value.

 

Test Method

Output Ripple & Noise Test:

  The output ripple is composed of fundamental frequency ripple and high frequency switching noise spikes. The fundamental switching frequency ripple (or basic ripple) is in the 100KHz to 1MHz range; the high frequency switching noise spike (or switching noise) is in the 10 MHz to 50MHz range. The switching noise is normally specified with 20 MHz bandwidth to include all significant harmonics for the noise spikes.

  The easiest way to measure the output ripple and noise is to use an oscilloscope probe tip and ground ring pressed directly against the power converter output pins, as shown below. This makes the shortest possible connection across the output terminals. The oscilloscope probe ground clip should never be used in the ripple and noise measurement. The ground clip will not only act as an antenna and pickup the radiated high frequency energy, but it will introduce the common-mode noise to the measurement as well.

  The standard test setup for ripple & noise measurements is shown in Figure E. A probe socket (Tektronix, P.N. 131.0258-00) is used for the measurements to eliminate noise pickup associated with long ground clip of scope probes.
