Product Brief Basic operation and functions The F400 family uses planar transformer technology to achieve high output current. The whole unit switches at the fixed frequency for a predictable EMI performance. The F400 Brick has many standard controls and protection functions. Input Power ( pin1, pin4 ) Input power Vin(+) must be connected to Positive input voltage pin1; Input power Vin(-) must be connected to Negative input voltage pin4. Output Power ( pin9, pin5 ) Output power Vout(+) must be connected to Positive output voltage pin9; Output power Vout(-) must be connected to Negative output voltage pin5. Pin 2 is the "Enable" pin, connecting a TTL compatible pin. A TTL control signal to this pin, according to the specification, will turn the unit on or off. The positive logic version turns on when pin 2 is at logic high, and turns off when pin 2 is at logic low. The unit is on when pin 2 is left open. Remote Sense ( pin 8, pin 6 ) Permits the user to maintain the accurate output voltage at the remote load terminals regardless of the line drop. The Sense(-) (pin6) and Sense(+) (pin8) should be connected at the load or at the point where the regulation is needed. ( shown on Fig. 2) On/Off ( pin 2 ) Permits the user to maintain unit On/Off, in order to properly sequence different power supplies and reduce power consumption during the standby condition. There is the remote control available, positive logic is referenced to Vin(-), and typical connections are shown in Fig 1. Fig 2: Remote Sense Circuit The remote sense feature of the unit compensates for voltage drop occurring between the output pins of the unit and load. The Sense(-) (pin5) and Sense(+)(pin7) should be connected at the load or at the point where regulation is required. Fig. 1: Typical Circuit for On/Off Function If remote Sense is not required, the Sense(-) pin must be connected to the Vout(-) pin (pin5), and Intronics, Inc. - 1400 Providence Highway, Building 2, Norwood, MA 02062 Tel.: 781-551-5500 • Fax: 781-551-5555 • www.intronics.com • Email: [email protected] F400 Rev1 1/31/03 F 200/400 FAMILY F400-48 Series 200/400W Full Bricks 48Vin 3.3, 5, 12, 15, 24Vout 400W the Sense(+) pin must be connected to the Vout(+) pin(pin 9) to ensure the unit will regulate at the specified output voltage. If these connections are not made, the unit’s output voltage will be higher than the specified value. Intronics, Inc. Product Brief When trimming up, care must be taken, not to exceed the unit OVP threshold. A typical circuit is shown in Fig. 3. The unit output over voltage protection senses the voltage across Vout(+) and Vout(-), and not across the sense lines, so the resistance between the output pins of the unit and the load should be minimized to prevent unwanted triggering of the OVP. When using the remote sense feature, the output voltage at the unit can be increased by as much as 10% above the normal rating, in order to maintain the required voltage across the load. Therefore, the designer must consider this condition. Also when using the remote sense function, the output power must be taken care of, as not to exceed the maximum power capability of the unit. Fig 3. Trim Up Output Voltage Circuit Trimming down the output voltage for a typical circuit, as shown on Fig. 4. Output Voltage Trim (pin 7) Permits the user to adjust the output voltage up or down to achieve the custom voltage or to make the output voltage margining. The adjustment range is from + 10% to -10%. Output voltage can be adjusted up or down, by connecting the Rtrim-up or Rtrim-down resistor as shown. Rtrim-up makes the output voltage go up to 10%; and the Rtrim-down makes the output voltage go down to 10%. Fig 4. Trim Down Output Voltage Circuit Leave Trim pin ( Pin 7) open for normal output voltage.

The unit will shut down when the input voltage drops below a threshold, and the unit will turn on when the input voltage goes to the upper threshold. The hysteretic voltage of the under voltage protection is 1V, normally from the 34V to 35V range. Output Over-current Protection ( OCP ) Over Temperature Protection ( OTP ) The unit will shut down when the base plate temperature exceeds the protection threshold. The unit will shut down under the base plate temperature over a 105°C condition to protect the unit from overheating. The OTP circuit will turn the unit off when OTP happens. Once the unit has shut down, it will restart at the cycle when the base plate temperature goes down. Typical Derating Specificatins (F400-48S3.3) (Heatsink information is on the following page) 70 The unit will shut down when the over current or short circuit condition exists. 60 W / O HS W / HS until the over current or short circuit condition is removed.

If the output voltage across Vout(+) (pin9) and Vout(-) (pin5) exceeds the threshold of the OVP circuitry, the unit has shut down which is caused by an OVP circuit, and the unit will never restart, and the output voltage is below 1V.

Product Brief Application information Input Source Impedance The unit has been designed to be stable with no external capacitors when used in a low inductance input and output circuit. However in many applications, the inductance with the distribution from the power source to the input of the unit can affect the stability of the unit. The addition of 470uF electrolytic capacitor with an Esr < 1Ω (at 100khz) across the input can ensure the stability of the unit. Also in many applications, the user has to use decoupling capacitors at the output load, to ensure the hold up time for the load. Safety Requirements and Considerations If the input source is non-SELV ( ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75 Vdc), for the unit output to be considered meeting the requirements of safety extra low voltage (SELV), all of the following must be met: • The input source is to be provided with reinforced insulation from any hazardous voltage, including the ac main. • The input pins of the unit are not operator accessible. • For whole system, for safety agencies requirements, and for the combination of the unit’s input side (primary side) and the unit’s output side (secondary side), verify that under a single fault, hazardous voltages do not appear at the unit’s output side (secondary side). Never ground either of the input pins of the unit without grounding one of the output pins. This may allow a non-SELV voltage to appear between the output pin and ground. The unit meets the American and International safety regulatory requirement UL1950. Basic insulation is also provided between the input side and the output side. To meet safety agencies requirements, an input line fuse must be used external to the unit. An 25A fuse or less with a normal blow rate must be used to meet the safety agencies requirements. A minimum 42LFM airflow should also be provided if the unit is intended to operate at full power without heatsink. • Heatsink Specifications (See previous page for derating information) Heatsink Material: Heatsink Dimensions: Aluminum Extrusion 2.44” x 4.60; x 0.78 Thermal Impedance = 3.0 ºC / W The converter can be operated at full load with appropriate forced air cooling or by using a lower resistance Heatsink.
