Data Sheet: PoweretaTM iQP Series –Single Output Quarter Brick

Operating Information:

Over-Current Protection: The power modules have current limit protection to protect the module during output overload and short circuit conditions. During overload conditions, the power modules may protect themselves by entering a hiccup current limit mode. The modules will operate normally once the output current returns to the specified operating range. There is a roughly 2ms delay from the time an overload condition appears at the module output until the hiccup mode will occur. A latched over- current protection option is also available. Consult the TDK Innoveta technical support for details.

Output Over-Voltage Protection: The power modules have a control circuit, independent of the main control loop, that reduces the risk of over voltage appearing at the output of the power module during a fault condition. If there is a fault in the main regulation loop, the over voltage protection circuitry will latch the power module off once it detects the output voltage condition as specified on the Electrical Data page. To remove the module from the latched condition, either cycle the input power or toggle the remote ON/OFF pin providing that over-voltage conditions have been removed. The reset time of the ON/OFF pin should be 500ms or longer.

The iQP Powereta family also offers an optional feature to allow non-latching 1- second hiccup mode over-voltage protection. Consult the TDK Innoveta technical support for details.

Thermal Protection: When the power modules exceed the maximum operating temperature, the modules will turn-off to safeguard the units against thermal damage. The module will auto restart as the unit is cooled below the over temperature threshold. A latched over-temperature protection option is also available. Consult the TDK Innoveta technical support for details.

Remote On/Off: - The power modules have an internal remote on/off circuit. The user must supply an open-collector or compatible switch between the Vin(-) pin and the on/off pin. The maximum voltage generated by the power module at the on/off terminal is 15V. The maximum allowable leakage current of the switch is 50uA. The switch must be capable of maintaining a low signal Von/off < 1.2V while sinking 1mA.

The standard on/off logic is negative logic. The module will turn on if pin 2 is connected to pin 3, and it will be off if pin 2 is left open. If the negative logic feature is not being used, pin 2 should be shorted to pin 3.

An optional positive logic is available. The power module will turn on if pin 2 is left open and will be off if pin 2 is connected to pin 3. If the positive logic circuit is not being used, terminal 2 should be left open.
