An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 6A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.

For all input sources, other than DC MAINS, where the input voltage is between 60 and 75V dc (Classified as TNV-2 in Europe), the following must be adhered to, if the converter’s output is to be evaluated for SELV: • The input source is to be provided with reinforced insulation from any hazardous voltage, including the AC mains. • One Vi pin and one Vo pin are to be reliably earthed, or both the input and output pins are to be kept floating. • Another SELV reliability test is conducted on the whole system, as required by the safety agencies, on the combination of supply source and the subject module to verify that under a single fault, hazardous voltages do not appear at the module’s output. 100 % Design Considerations The power module has ELV (extra-low voltage) outputs when all inputs are ELV. The power module should be connected to a low ac-impedance source. A highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 37, a 33μF electrolytic capacitor (ESR<0.7Ω at 100kHz), mounted close to the power module helps ensure the All flammable materials used in the manufacturing of these modules are rated 94V-0, and UL60950 A.2 for reduced thickness. The input to these units is to be provided with a maximum 6A time- delay in the unearthed lead.

Positive logic 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, device code suffix “1”, turns the module off during a logic high and on during a logic low. To turn the power module on and off, the user must supply a switch (open collector or equivalent) to control the voltage (Von/off) between the ON/OFF terminal and the VIN(-) terminal (Figure 40). Logic low is –0.7V ≤ Von/off ≤ 1.2V. The maximum Ion/off during a logic low is 1mA, the switch should be maintain a logic low level while sinking this current. During a logic high, the typical Von/off generated by the module is 15V, and the maximum allowable leakage current at Von/off = 15V is 10μA. If not using the remote on/off feature: For positive logic, leave the ON/OFF pin open. For negative logic, short the ON/OFF pin to VIN(-). The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Maximum rated power = Vo,set x Io,max).

The following equation determines the required external resistor value to obtain a percentage output voltage change of Δ% Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim.

At 48Vin (+/- 2.5V), EQW series modules can be trim down to 20% over the entire temperature range. This allows for margining the unit during manufacturing process if the set point voltage is lower than the standard output voltage. Please consult your local Lineage Power field application engineer for additional details. The voltage between the Vo(+) and Vo(–) terminals must not exceed the minimum output overvoltage protection value shown in the Feature Specifications table. This limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjustment trim. Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Maximum rated power = Vo,set x Io,max). 14 Data Sheet December 12, 2008 EQW012/020/023/025 Series, Eighth-Brick Power Modules: 36 - 75Vdc Input; 1.2Vdc to 5Vdc Output; 12A to 25A Output o Feature Description (Continued) operation this temperature should not exceed 115 C. The output power of the module should not exceed the rated power for the module (Vo, set x Io, max). Tref Overcurrent Protection To provide protection in a fault (output overload) condi¬tion, the module is equipped with internal current-limiting circuitry, and can endure current limiting continuously. At the instance of current-limit inception, the output current begins to tail-out. When an overcurrent condition exists beyond a few seconds, the module enters a “hiccup” mode of opera¬tion, whereby it shuts down and automatically attempts to restart upon cooling. While the fault condition exists, the module will remain in this hiccup mode, and can remain in this mode until the fault is cleared. The unit operates normally once the output current is reduced back into its specified range. Output Over Voltage Protection The output overvoltage protection clamp consists of control circuitry, independent of the primary regulation loop, that monitors the voltage on the output terminals. This control loop has a higher voltage set point than the primary loop (See the overvoltage clamp values in the Feature Specifications Table). In a fault condition, the overvoltage clamp ensures that the output voltage does not exceed Vo,ovsd, max. This provides a redundant voltage-control that reduces the risk of output overvoltage. Input Undervoltage Lockout At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage between the undervoltage lockout limit and the minimum operating input voltage. Air Flow Figure 43. Tref Temperature Measurement Location. Please refer to the Application Note “Thermal Characterization Process For Open-Frame BoardMounted Power Modules” for a detailed discussion of thermal aspects including maximum device temperatures. Heat Transfer via Convection Increased airflow over the module enhances the heat transfer via convection. Derating figures showing the maximum output current that can be delivered by each module versus local ambient temperature (TA) for natural convection and up to 2m/s (400 ft./min) are shown in the respective Characteristics Curves section. Overtemperature Protection To provide protection under certain fault conditions, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the thermal reference point o Tref (Figure 43), exceeds 125 C (typical), but the thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restarts after it cools down. Thermal Considerations The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel.

For Pb solder, the recommended pot temperature is 260°C, while the Pb-free solder pot is 270°C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process.

Surface Mount Information Pick and Place The SMT versions of the EQW series of DC-to-DC power converters use an open-frame construction and are designed for surface mount assembly within a fully automated manufacturing process. The EQW-S series modules are fitted with a Kapton label designed to provide a large flat surface for pick and placing. The label is located covering the center of gravity of the power module. The label meets all the requirements for surface-mount processing, as well as meeting UL safety agency standards. The label will withstand reflow temperatures up to 300°C. The label also carries product information such as product code, date and location of manufacture. Figure 47. Pick and Place Location.

Reflow Soldering Information The surface mountable modules in the EQW family use our newest SMT technology called “Column Pin” (CP) connectors. Figure 48 shows the new CP connector before and after reflow soldering onto the end-board assembly. EQW Board Insulator Solder Ball End assembly PCB Figure 48. Column Pin Connector Before and After Reflow Soldering . The CP is constructed from a solid copper pin with an integral solder ball attached, which is composed of tin/lead (Sn63/Pb37) solder for non-Z codes, or Sn/Ag3.8/Cu0.7 (SAC) solder for –Z codes. The CP connector design is able to compensate for large amounts of co-planarity and still ensure a reliable SMT solder joint. Typically, the eutectic solder melts at 183oC (Sn/Pb solder) or 217-218 oC (SAC solder), wets the land, and subsequently wicks the device connection. Sufficient time must be allowed to fuse the plating on the connection to ensure a reliable solder joint. There are several types of SMT reflow technologies currently used in the industry. These surface mount power modules can be reliably soldered using natural forced convection, IR (radiant infrared), or a combination of convection/IR. The following instructions must be observed when SMT soldering these units. Failure to observe these instructions may result in the failure of or cause damage to the modules, and can adversely affect long-term reliability.
