data sheet june 17, 2009 quk240 series power modules; dc-dc converters 36 ? 55vdc input; 9vdc output; 240 w lineage power 8 feature description remote on/off two remote on/off options are available. positive logic remote on/off turns the module on during a logic-high voltage on the on/off pin, and off during a logic low. negative logic remote on/off turns the module off during a logic high and on during a logic low. negative logic, device code suffix "1," is the factory-preferred configuration. to turn the power module on and off, the user must supply a switch to control the voltage between the on/off terminal and the vi (-) terminal (von/off). the switch can be an open collector or equivalent (see figure 12). a logic low is von/off = 0 v to i.2 v. the maximum ion/off during a logic low is 1 ma. the switch should maintain a logic-low voltage while sinking 1 ma. during a logic high, the maximum von/off generated by the power module is 15 v. the maximum allowable leakage current of the switch at von/off = 15v is 50 a. if not using the remote on/off feature, perform one of the following to turn the unit on: for negative logic, short on/off pin to vi(-). for positive logic: leave on/off pin open. v o (+) v o (?) v i (?) + ? i on/off on/off v i (+) loa d v on/off figure 12. remote on/off implementation overcurrent protection to provide protection in a fault output overload condition, the module is equipped with internal current-limiting circuitry and can endure current limiting for a few mili-seconds. if the overcurrent condition persists beyond a few milliseconds, the module will shut down an d remain latched off. the overcurrent latch is reset by either cycling the input power or by toggling the on/off pin for one second. if the output overload condition still exists when the module restarts, it will shut down again. this operation will continue indefinitely until the overcurrent condition is corrected. an auto-restart option is also available. an auto- restart feature continually attempts to restore the operation until fault condition is cleared. input undervoltage lockout at input voltages above or below the input under/over voltage lockout limits, module operation is disabled. the module will begin to operate when the input voltage level changes to within the under and overvoltage lockout limits. overtemperature protection these modules feature an overtemperature protection circuit to safeguard against thermal damage. the circuit shuts down and latches off the module when the maximum device reference temperature is exceeded. the module can be restarted by cycling the dc input power for at least one second or by toggling the remote on/off signal for at least one second. input/output overvoltage protection the input/output overvoltage protection circuit is designed to shut down the module when the input voltage exceeds the overvoltage threshold. the module will resume operation when the input voltage enters the normal input operating range.

(200 ft./min.)
