Components taller than ~ 2mm in front of the module can deflect airflow and possibly create hotspots. • Significant cooling is achieved through conductive flow from the modules I/O pins to the host PCB. Sufficiently large traces connecting the dc-dc converter to the source and load will help ensure thermal derating performance will meet or exceed the derating curves published in this datasheet. • If the module is expected to be operated near the load limits defined in the derating curves, insystem verification of module derating performance should be performed to ensure long-term system reliability. Peak temperatures are to be measured using infrared thermography or by gluing a fine gauge (AWG #40) thermocouple at the Tref location(s) shown below. Temperature at the specified location(s) should be kept below 123ºC for open frame units, 105ºC for encapsulated modules in order to maintain optimum converter reliability. Open Frame Encapsulated Input Undervoltage Lockout • The converter is disabled until the input voltage has exceeded the UVLO turn-on threshold. Once the input voltage exceeds this level (see Input Under-Voltage Lock-out in Electrical Specifications table) the module will commence soft-start. Hysteresis of (typically) 1-3 volts minimizes the likelihood of pulling the input voltage below the turn-off threshold during startup which could create an undesirable on/off cycling condition. The converter will continue to operate until the input voltage subsequently falls below the UVLO turn-off threshold. Enable Pin Function • The module has a remote enable function that allows it to be turned on or off remotely. The Enable pin is referenced to the negative input pin (-Vin) of the converter. Modules can be ordered with either negative or positive enable. • The negative enable option the module will not turn on unless the enable pin is connected to – Vin. The positive enable option allows the converter to turn on as soon as voltage sufficient to exceed the UVLO of the converter has been applied to the input terminals. In this case the module is turned off by connecting the Enable pin to –Vin. On/off thresholds are located in the Electrical Specifications table. www.dcdc.com 603-893-2330 - 11 - 11 - Technical Datasheet CP30_1160005 Application Notes (cont) Output Overvoltage Protection • The module has an independent feedback loop that will disable the output of the converter if a voltage greater than about 125% of the nominal set point is detected. When this threshold is reached, the converter will shut down and remain off for the amount of time specified by the Auto-Restart Period. The converter will attempt a restart once this period of time has elapsed. Output Overtemperature Protection • To provide protection under certain fault conditions, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the average PCB temperature exceeds approx. 135ºC, but the thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restart once it has cooled below the shutdown temperature minus hysteresis (typically 20 deg C.) SMT Version Layout Considerations (if applicable) • Copper traces with sufficient cross-section must be provided for all output & input pins. SMT pads tied to internal power/ground planes must have multiple vias around each SMT pad to couple expected current loads from module pins into internal traces/planes. One 0.024” (0.6mm) diameter via for each 4A of expected source or load current must be provided as close to the termination as possible, preferably in the direction of current flow from SMT pad to load. Vias must be at least 0.024” (0.6 mm) away from the SMT pad to prevent solder from flowing into the vias. • SMT pads on the host card are to be 0.075” (1.9mm) diameter. Solder paste screen opening should be 0.070” diameter and the screen should be 0.006” (0.15 mm) thick (other thicknesses are possible; 0.006” provides a good compromise between solder volume and coplanarity compensation.) Paralleling Converters • Modules may be paralleled but it is recommended that the total power draw not exceed the output power rating of a single module. External sharing controllers are recommended for reliability and to ensure equal distribution of the load to the converters. www.dcdc.com 603-893-2330 - 12 - 12 - Technical Datasheet CP30_1160005 Application Notes (cont) EMC Compliance To meet Class B compliance for EN55032 (CISPR 32) or FCC part 15 sub part j, the following input filter is required: Figure 18.
