Technical Specification NQ16W50SKA10 6.0-16.0V 0.75-5.0V Input 10 Amp Outputs Non Current Isolated SMT Surface Mount The NiQor SMT DC/DC converter is a non-isolated buck regulator, which employs synchronous rectification to achieve extremely high conversion efficiency. 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 page 12).

C 03/23/10 Page 8 Input: Outputs: Current: Package: 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. For a desired increase of the nominal output voltage, the value of the resistor should be: Rtrim= up VDES - 0.7525 VOUT = 0.7525 + The NiQor series of SIPs and SMT converters uses the established industry standard footprint and pin-out configurations. 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. 10500 _ 1000 (W) or 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. CONTROL FEATURES 6.0 - 16.0V 0.75 - 5.0V 10A SMT 10500 Rtrim-up + 1000 (W) where V DES = Desired Output Voltage 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. 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 0.7525V using an external resistor, connect the resistor Rtrim-up between the TRIM and the Ground pin according to the diagram below. Vout Sense+ Vin On/Off Gnd Trim Rtrim-up PROTECTION FEATURES 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 over-current 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, the NQ16 series 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, in the wide-trim W50 model. The shutdown point is fixed on standard option. SKA also offers adjustable OVP set point.

C 03/23/10 Page 9 Input: Outputs: Current: Package: Technical Specification 6.0 - 16.0V 0.75 - 5.0V 10A SMT 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. 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. In the SKA10 (surface mount) converters Cin = 30µF 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. Figure F: Converter with Additional Output Capacitance Thermal Performance (SKA10): While impossible to be exact, a simplified thermal model for the mounted converter is detailed below. Figure E: NQ16 converter with Input Filter 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. Cin has a reactance of 10-20mW at the 300kHz 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 SKA10 series of converters. The VMA16 series has this capacitance included internally. In many applications, however, additional external output capacitance is required to reduce the response to load transients to an allowable level. Product # NQ16W50SKA10 Phone 1-888-567-9596 Figure G: Thermal Model for NQ16 Surface Mount • Rt_J-Pcb models the conduction of heat from the converter’s hottest junction to the converter’s PCB at large. It is about 3oC/W for converters running at higher output voltage, and about 4oC/W for lower voltage converters. • Rt_Pcb-Amb models the power dissipation from converter PCB to the air stream. It ranges from about 15oC/W at 400LFM to about 25oC/W 100LFM. • Rt_Pcb-Feet expresses the thermal path from the converter’s PCB though its mounting feet; it is about 3oC/W. • Rt_spread models the heat spreading on the PCB to which the converter is mounted and is largely dependent upon the construction and layout of that PCB. • T_mount is the temperature of that PCB in the greater vicinity of the converter. As is evident, the values for Rt_spread and T_mount will have great effect upon the thermal operation of the converter. With Rt_Pcb-Amb being 5 to 8 times as large as Rt_Pcb-Feet, in most applications these converters will be predominantly cooled via thermal conduction through their feet. Airflow and T_Amb will have only a minimal cooling effect. www.synqor.com Doc.# 005-NS15W10 Rev. C 03/23/10 Page 10 Input: Outputs: Current: Package: Technical Specification • Rt_spread should be minimized. Attach the converter to large copper planes, on multiple layers, with multiple vias near the mounting feet. • T_mount should also be minimized. Place the converter far enough away from other sources of heat on the PCB so that it is as cool as practical. • If operation near derating limits is even suspected, thermal performance should be verified with the unit mounted in its intended manner and powered in circuit with all neighboring circuitry active. Attach a thermocouple to the converter’s hotspot as shown in Figures 4, 6, and 8 in the Performance Curves section. 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. 6.0 - 16.0V 0.75 - 5.0V 10A SMT Reflow Soldering Guidelines: Figure J shows a typical reflow profile for a eutectic solder process. 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. 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. RoHS Compliance: The EU led RoHS (Restriction of Hazardous Substances) Directive bans the use of Lead, Cadmium, Hexavalent Chromium, Mercury, Polybrominated Biphenyls (PBB), and Polybrominated Diphenyl Ether (PBDE) in Electrical and Electronic Equipment. This SynQor product is 6/6 RoHS compliant. For more information please refer to SynQor’s RoHS addendum available at our RoHS Compliance / Lead Free Initiative web page or e-mail us at [email protected]. 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 Maximum Temperature (+210-260 C) size, tip style, handling speed, and placement pressure should be optimized for best results. A conformal tipped placement nozzle design Eutectic Solder Melting Point (+183 C) is recommended. Coplanarity of better than 0.004” (0.1mm) is achieved through the SMT (+150-155 C) NiQor’s terminal design. o o o Pre-heat •< Reflow Soak 2.5 C/sec o Cool Down • 0.5-0.6oC/sec • 1.3-1.6oC/sec • 60 • 30 to 90 sec., typ., 2 min max to 60 sec., typ., 90 sec max 2 to 4 min.
