4.9 - 9 Vdc / 9 - 18 Vdc / 18 - 36 Vdc / 36 - 72 Vdc (NEW)
| Isolated, Regulated Outputs High Efficiency, Low Ripple 0°C to +85°C Operating Temperature, Base Plate Miniature - Low Profile (2.5" x 1.55" x 0.5") - PCB Mountable High Reliability DC-DC Converters |
|
||||||||||||
|
The QP Series of Miniature Power DC/DC Converters operates over wide input voltage ranges (4.5-9Vdc, 9-18Vdc, 18 - 36 Vdc, and 36 - 72 Vdc) while maintaining tight output regulation and low ripple. Safety Features of QP Modules include: Overtemperature, Input Under/Over voltage, Output Overcurrent and Short Circuit Protection. Units in QP Series also feature Remote Shutdown, Trim capability, 3Vref, External Bias and do not use OptoCouplers in the feed-back loop. Fixed Frequency operation enables parallel connection for higher power requirements. QP Series units are fully encapsulated for rugged operation.

- Remote Shutdown: Converter is turned off when Pin # 2 (SHDN) is clamped to Pin # 1 within less than 0.4 V
|
|
|
- External Bias Function
Ex.B Voltage = 17...20Vdc; Ex.B Current = 20mA (typical)
|
|
External Bias should be used in Capacitor Charging applications. The QP unit will not start-up under a short-cuicuit condition because the Internal Bias Supply cannot develop the required start-up voltage. To charge up a large capacitor, an external bias voltage should be used only until the output voltage, Vout, reached 90 - 95% of its nominal value and therefore the internal bias voltage has come up and is able to sustain converter operation.
Note that during External Bias operation, output overload and short circuit protection are disabled and for this reason it is highly recommended - as shown in diagram - to disable the External Bias supply after Vout reaches its nominal value and allow from that moment on for the internal bias voltage operation. While on internal bias operation, overload and short circuit protections are restored.
For additional information, see Application Notes.

PIN DESCRIPTION Pin # 1 (-IN): Negative Input Voltage to the unit, 9-18V (12QP Series), 18-36V (24 QP Series), or 36-72V (48QP Series). Units are Input UV/OV protected, nonlatched shut-down. Pin # 2 (SHDN): When pulled below 0.4Vdc will cause the unit to shut down, non-latching. Pin # 3 (VREF): 3Vref generated on board. Range 2.8Vdc to 3.2Vdc Current sourcing capability: 10mA max. Pin # 4 (TRIM): Connecting it through a resistor to VREF will reduce V OUT. Adjusting range is max. - 5% V OUT. Pin # 5 (EX.B): This pin is a direct path to the controller IC's Vcc and should not exceed 20Vdc otherwise the IC will be damanged. External Bias (Ex.B) will enable applications where the unit has to start up under an overload or short-circuit condition (like capacitor charging applications). Overload conditions will prevent internal bias supply to develop the start-up voltage due to the hiccup protection mode and unit will not start. Required voltage for Ex.B start up: 17 to 20Vdc. Caution: when operated with Ex.B, the unit loses overload and short circuit protection. Do not connect if Pin # 5 is not used. Pin # 6 (+IN): Positive Input Voltage to the unit. Pin # 7 (+OUT): Positive Output Voltage. A minimum 10% load across the output is required in order to provide regulation. Output is clamped with Zener diodes at a 120% V OUT (typical) to limit overshoot in case of no load operation. Pin # 8 (-OUT): Negative Output Voltage |
