The NiQor family of converters are used predominately in DPA systems using a front end DC/DC high power brick (48Vin to low voltage bus). The non-isolated NiQor converters are then used at the point of load to create the low voltage outputs required by the design. The wide trim module can be programmed to a variety of output voltages through the use of a single external resistor. RoHS compliant see last page.

C 10/03/08 Page 7 Technical Specification BASIC OPERATION AND FEATURES The NiQor series non-isolated converter uses a buck-converter that keeps the output voltage constant over variations in line, load, and temperature. The NiQor modules employ synchronous rectification for very high efficiency. Dissipation throughout the converter is so low that it does not require a heatsink or metal baseplate for operation. The NiQor converter can thus be built more simply and reliably using high yield surface mount techniques on a single PCB substrate. The NiQor series of SIPs and SMT converters uses the established industry standard footprint and pin-out configurations. Input: Outputs: Current: Package: 6.0 - 15.0V 0.8 - 5.0V 30A SMT For a desired increase of the nominal output voltage, the value of the resistor should be: Rtrim-up = 1200 VDES - 0.8 or 1200 _ 100 (W) VOUT = 0.8+ where Rtrim-up + 100 (W) VDES = Desired Output Voltage CONTROL FEATURES REMOTE ON/OFF: The ON/OFF input permits the user to control when the converter is on or off. There are currently two options available for the ON/OFF input described in the table below. Others may become available if demand exists. To maintain the accuracy of the output voltage over load current, it is vital that any trim-up resistor be terminated directly to the converter’s ground foot, not at the connection to the load. A separate Kelvin connection to the PCB pad for the ground foot is optimal. Trim-down resistors should be terminated at the converter’s Sense+ pin. We do not recommend bypassing the trim pin directly to ground with a capacitor. The voltage gain from the trim pin to output is rather large, 15:1. Ground bounce through a bypass capacitor could introduce significant noise to the converter’s control circuit. PROTECTION FEATURES OUTPUT VOLTAGE TRIM: The TRIM input permits the user to adjust the output voltage according to the trim range specifications by using an external resistor. If the TRIM feature is not being used, leave the TRIM pin disconnected. TRIM-UP: To increase the output voltage from the nominal setpoint of 0.8V using an external resistor, connect the resistor Rtrim-up between the TRIM and the Ground pin according to the diagram below. Input Under-Voltage Lockout: The converter is designed to turn off when the input voltage is too low, helping avoid an input system instability problem, described in more detail in the application note titled “Input System Instability”. The lockout circuitry is a comparator with DC hysteresis. When the input voltage is rising, it must exceed the typical Turn-On Voltage Threshold value (listed on the specification page) before the converter will turn on. Once the converter is on, the input voltage must fall below the typical Turn-Off Voltage Threshold value before the converter will turn off. Output Current Limiting: To provide protection in an output over load fault condition, the unit is equipped with internal overcurrent protection. When the over-current protection is triggered, the unit enters hiccup mode. The units operate normally once the fault condition is removed. Internal Over-Voltage Protection: To fully protect from excessive output voltage, this series contains contains an Output Over-Voltage Shutdown circuitry. This OVP is independent of the trimmed setpoint. As such, the converter’s load is protected from faults in the external trim circuitry (such as a trim pin shorted to ground). Since the setpoint of this OVP does not track trim, it is set at 6.0V. For more detailed information contact SynQor technical support.

C 10/03/08 Page 8 Technical Specification Over-Temperature Shutdown: A temperature sensor on the converter senses the average temperature of the module. The thermal shutdown circuit is designed to turn the converter off when the temperature at the sensed location reaches the Over-Temperature Shutdown value. It will allow the converter to turn on again when the temperature of the sensed location falls by the amount of the Over-Temperature Shutdown Restart Hysteresis value. Input: Outputs: Current: Package: 6.0 - 15.0V 0.8 - 5.0V 30A SMT APPLICATION CONSIDERATIONS Input Filtering/Capacitance/Damping: The filter circuit of Figure E is often added to the converter’s input to prevent switching noise from reaching the input voltage bus. Figure H: Converter with Additional Output Capacitance Active Load Sharing: For additional power requirements, the SGA30 series of converters have a parallel feature available. To implement forced load sharing, the following connections should be made: • The share pins of all units in parallel must be connected together. The path of these connections should be as direct as possible. • All ON/OFF pins should be connected together. Figure E: converter with Input Filter In the SGA30 (surface mount) converters Cin = 20µF of high quality ceramic capacitors. With Lin of 1µH, Cd should be 100-200µF and Rd should be 0.1-0.2W, in most applications. For more information on designing the input filter and choosing proper values, contact SynQor technical support. Adding significant external pure ceramic capacitance directly across the converter’s input pins is not recommended. Parasitic inductance associated with the input pin geometry and PCB traces can create a high-Q CLC circuit with any external capacitors. Just a few nano-Henries of parasitic inductance can create a resonance (or an overtone) near the converter’s switching frequency. To avoid this high-frequency resonance, any external input filter should exhibit a net source impedance of at least 20mW resistive through this frequency range. This requirement is easily met with the damping elements discussed above. Adding a small amount (a few µF) of high-frequency external ceramic will not violate it. If using converters at higher powers, consider the ripple current rating of Cd. Contact SynQor technical support for details. Output Capacitance: It is recommended to add at least 100µF of capacitance, with an ESR in the 0.1W range, to the output of the SGA30 series of converters. In many applications, however, additional external output capacitance is required to reduce the response to load transients to an allowable level. For minimal overshoot upon recovery, Cd should be related to the minimum in-circuit net ESR. For more detailed derivations of these values contact SynQor technical support. The share bus is not designed for redundant operation and the system will be non-functional upon failure of one of the units when multiple units are in parallel. When not using the parallel feature, leave the share pin open. SURFACE MOUNT INFORMATION PCB Layout Considerations: SynQor recommends that the customer use a non-solder mask defined pad design. The minimum recommended pad size is 0.074” x 0.122” (1.88mm x 3.1mm) and the maximum pad size is 0.095” x 0.140” (2.41mm x 3.56mm), see the mechanical diagram on page 2. Interconnection to internal power planes is typically required. This can be accomplished by placing a number of vias between the SMT pad and the relevant plane. The number and location of the vias should be determined based on electrical resistance, current and thermal requirements. “Via-in-pad” design should be avoided in the SMT pads. Solder mask should be used to eliminate solder wicking into the vias. Pick and Place: The NiQor surface mount modules are designed for automated assembly using standard SMT pick and place equipment. The modules have a centrally located inductor component with a flat surface area to be used for component pick-up. The units use open frame construction and have a low mass that is within the capability of standard pick and place equipment. Those modules however have a larger mass than most conventional SMT components and so variables such as nozzle size, tip style, handling speed, and placement pressure should be optimized for best results. A conformal tipped placement nozzle design is recommended. Coplanarity of better than 0.004” (0.1mm) is achieved through the SMT NiQor’s terminal design.

Due to variations in customer applications, materials and processes, it is not feasible for SynQor to recommend a specific reflow profile. The customer should use this profile as a guideline only. Since the NiQor surface mount modules have a larger thermal mass and lower thermal resistance than standard SMT components, it may be necessary to optimize the solder reflow profile based on limitations of the other components on the customer board. Sufficient reflow time must be allowed to fuse the plating on the connection to ensure a reliable solder joint. The solder reflow profile should be confirmed by accurately measuring the SMT interconnect leads. Maximum case temperature of 260°C (exposure for 5 seconds or less) is not exceeded for the NiQor units. Moisture Sensitivity: The NiQor surface mount modules have an MSL rating 1 per IPC/ JEDEC J-STD-033A.

Figure J: Typical Eutectic (96.5Sn/3.0Ag/0.5Cu) Solder Profile Cleaning and Drying: When possible, a no-clean solder paste system should be used to solder the NiQor SMT units to their application board. The modules are suitable for aqueous washing, however, the user must ensure sufficient drying to remove all water from the converter before powering up. Inadequate cleaning and drying can affect the reliability of the converter and the testing of the final assembly. Product # NQ15W50SGA30 Phone 1-888-567-9596 www.synqor.com Doc.# 005-2NS163E Rev.
