data sheet march 26, 2008 euk240 series power modules; dc-dc converters 36 ? 60vdc input; 9.6vdc output; 240w 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 logic low. negative logic remote on/o ff 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 swit ch 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 16). a logic low is von/off = -0.3 v to 0.8 v. the maximum ion/off during a logic low is 10 ma. the switch should maintain a logic-low voltage while sinking 10 ma. during logic high, the maximum von/off generated by the power module is 4.7 v. the maximum allowabl e leakage current of the switch at von/off = 2.0v is 0.7 ma. 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 16. circuit configuration for using remote on/off implementation. over-current protection to provide protection in an ou tput overload condition, the module is equipped with internal current-limiting circuitry and can endure current limiting for unlimited duration. if the output current exceeds the current limit inception value, the module enters into the hiccup (auto-restart) mode operatio n, where it shuts down and automatically attempts to restart. as long as the fault condition exists, the module will remain in this hiccup mode, and can sustain this mode of operation until the over-current fault condition is corrected. input under-voltage lockout at input voltages below the input under voltage lockout limit, the module operation is disabled. the module will begin to operate at an input voltage above the under voltage lockout turn-on threshold. over-temperature protection these modules featur e an over-temperature protection circuit to safeguard against thermal damage. the protection circuit shuts down the module when the maximum device reference temperature is exceeded. when the module cools down and the reference device temperature falls below the recovery threshold, the module will resume operation. over-voltage protection the input/output over-voltage protection circuit is designed to shut down the module when the input voltage exceeds the over-voltage threshold. the module will resume operation when the input voltage enters the normal input operating range short circuit protection the power modules shall sustain no damage when subjected to a short circuit of any duration on its output. the output of the module shall recover automatically in a hiccup (auto-restart) manner identical to that described in the over-current protection section. pre-bias immunity the startup/shutdown charac teristics of the module accommodates external voltage source clamping on the output via external diodes without exhibiting non- monotonic startup (see figure 17). the monotonic startup of the module wi ll not be affected by the customer application of t he pre-biasing of the output. during shutdown an internal feature implemented in the module ensures there will be no reverse current. during hiccup operation, the reverse current protection will be enabled. figure 17. pre-bias immunity configuration. module l o a d vs vout
