Current is measured at the input of the module. Figure 23: Input reflected-ripple current test setup To maintain low-noise and ripple at the input voltage, it is critical to use low ESR capacitors at the input to the module. Figure 26 shows the input ripple voltage (mVp-p) for various output models using 2x100 uF low ESR tantalum capacitors (KEMET P/N:T491D107M, 100uF/16V or equivalent) or 2x22 uF very low ESR ceramic capacitors (TDK P/N:C3225X7S1C226MT, 22uF/16V or equivalent).

For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a maximum 10A time-delay fuse in the ungrounded lead. Remote On/Off The IPM series power modules have an On/Off control pin for output voltage remote On/Off operation. The On/Off pin is an open collector/drain logic input signal that is referenced to ground. When On/Off control pin is not used, leave the pin unconnected. The remote on/off pin is internally connected to +Vin through an internal pull-up resistor. Figure 27 shows the circuit configuration for applying the remote on/off pin. The module will execute a soft start ON when the transistor Q1 is in the off state. The typical rise for this remote on/off pin at the output voltage of 0.9V and 3.3V are shown in Figure 17 and 18. 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. Pre-Bias Startup Capability The IPM would perform the monotonic startup into the pre-bias loads; so as to avoid a system voltage drop occur upon application. In complex digital systems an external voltage can sometimes be presented at the output of the module during power on. This voltage may be feedback through a multi-supply logic component, such as FPGA or ASIC. Another way might be via a clamp diode as part of a power up sequencing implementation. Output Voltage Programming The output voltage of IPM can be programmed to any voltage between 0.9Vdc and 3.3Vdc by connecting one resistor (shown as Rtrim in Figure 28, 29) between the TRIM and GND pins of the module to trim up (0.9V ~ 3.3V) and between the Trim and +Output to trim down (0.8V ~ 0.9V). Without this external resistor, the output voltage of the module is 0.9 Vdc. To calculate the value of the resistor Rtrim for a particular output voltage Vo, please use the following equation: Trim up Rtrim = Vo Vin IPM On/Off 7.0 Vadj. –0.9 - 0.187 (KΩ) 2.0 0.9 – Vadj. - 10.187 (KΩ) Trim Down RL Rtrim = Q1 GND Rtrim is the external resistor in KΩ Vout is the desired output voltage Figure 27: Remote on/off implementation DS_IPM04C0A0R06_08242006 8 FEATURES DESCRIPTIONS (CON.) For example: to program the output voltage of the IPM module to 3.3Vdc, Rtrim is calculated as follows: Rtrim = 7.0 3.3 –0.9 - 0.187 (KΩ) Rtrim = 2.729 KΩ Figure 28: Trim up Circuit configuration for programming output voltage using an external resistor IPM can also be programmed by applying a voltage between the TRIM and GND pins (Figure 30). The following equation can be used to determine the value of Vtrim needed for a desired output voltage Vo: Vout Rtrim Vtrim = 0.7168 – 0.0187Vo Load Trim Vtrim is the external voltage in V Vo is the desired output voltage For example, to program the output voltage of a IPM module to 3.3 Vdc, Vtrim is calculated as follows GND Figure 29: Trim down Circuit configuration for programming output voltage using an external resistor Vtrim = 0.7168 – 0.0187 x 3.3 Vtrim = 0.6551V Figure 30: Circuit configuration for programming output voltage using external voltage source DS_IPM04C0A0R06_08242006 9 FEATURE DESCRIPTIONS (CON.) Table 1 provides Rtrim values required for some common output voltages, while Table 2 provides value of external voltage source, Vtrim, for the same common output voltages. By using a 0.5% tolerance resistor, set point tolerance of ±2% can be achieved as specified in the electrical specification. Table 1 The amount of power delivered by the module is the voltage at the output terminals multiplied by the output current. When using the trim feature, 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 must not exceed the maximum rated power (Vo.set x Io.max ≤ P max).

To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. Thermal Testing Setup Delta’s DC/DC power modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment. This type of equipment commonly uses vertically mounted circuit cards in cabinet racks in which the power modules are mounted. Figure 33: Temperature measurement location * The allowed maximum hot spot temperature is defined at 116℃. The following figure shows the wind tunnel characterization setup. The power module is mounted on a test PWB and is vertically positioned within the wind tunnel. The height of this fan duct is constantly kept at 25.4mm (1’’). Thermal Derating Heat can be removed by increasing airflow over the module. To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected.
