Introduction
APA06 series power SIPs are non-isolated DCDC modules with wide input voltage range featuring high efficiency up to 88%@2.5Vout, 89%@3.3Vout. APA06 series comes in 3V to 5.5V input range and are capable of providing up to 20W of output power in a small size 2.5in.x0.55in.x0.33in. The module uses a wide input range covering the old 3.3V input series and 5V input series, also provides 1.2V, 1.5V, 1.8V, 2.1V, 2.5V and 3.3V output voltage with 6A output current. APA06 series converters feature high efficiency, high power density, wide operating environment temperature range, and easy installation. The typical efficiencies are 89% for 3.3Vout, 88% for 2.5Vout, 86% for 2.1Vout, 83% for 1.8Vout, 81% for 1.5Vout, 78% for 1.2 Vout. The operating environment temperature can reach 55C with natural convection. With adjustable output, CNT function (positive or negative is optional), remote sense, OCP, short circuit protection and power good signal, the series are especially suitable for Telecom, Datacom, work station, severs and distributed power supply systems. The APA06 series is designed to meet UL, TUV, and CSA certifications. UL has been approved.

Input Characteristics Output Characteristics
The APA06 power module has no internal fuse. An external fuse must always be employed! To meet international safety requirements, an input line fuse should be used. Input wires and copper coil must be capable of conducting a current of 1.5 times the value of the fuse. If one of the input lines is connected to chassis ground, then the fuse must be placed in the other input line. A fuse with ratings of 15A is recommended for 2.5V and 3.3V output, and 10A for APA06 other products. CNT Function The APA06 provides CNT function allowing the user to turn the output on and off using an external circuit such as figure 1 and figure 2. The control voltage-threshold is: 1.8V. For negative control(negative logic N or positive logic P are optional), applying a voltage less than 1.8V to the CNT pin will enable the output, while applying a voltage greater than 2.4V will disable it. If not using CNT feature, leave the CNT pin open. The maximum voltage that can be applied to the control pin is 12 volts. Remote Sensing When the load can not be placed close to converter output pin, voltage drop will occur in distribution. This voltage drop can be compensated using sense lead. As shown in figure 3, connecting sense pin close to the load, when the load changes, the module will automatically adjust the real output to maintain the constant voltage on the load. If not using the remote sense pin, leave it open.

Output Trimming Trimming Output can be externally trimmed by using either method shown in figure 4. Users can increase or decrease the output voltage set point of a module by connecting an external resistor between the TRIM pin and either the +Vout or GND pins. The trim resistor should be positioned close to the module. If not using the trim feature, leave the TRIM pin open. Trimming up or down by more than 16% of the nominal output may cause the converter to work improperly. The trim formula for different output voltage are shown in figure 4 next page.

Parallel application APA06 series DC-DC converters can be used in parallel (at most two modules). You can use diode (or not) in output circuit. The parallel two power module can (total) output the largest current 7.5~8A in a long time. If the load is over 8A, the output will be in hiccup over-current protection. The application circuit is shown as in Figure 5.

Fig.4 Output Voltage Set-point Adjustment Output Over-Current Protection APA06 series DC-DC converters feature current limiting with a threshold is between 8.4A and 10.8A. These modules can tolerate short circuit conditions (continuously of transient). When the overcurrent condition is removed, the converter will automatically restart. Power Good signal min max High-level 2.1V Low-level 1.05V Inner resistance = 5.1k.
Safety Considerations
For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL1950, CSA C22.2 No. 950-95, and VDE 0805 (EN60950, IEC950). For the module's output to be considered meeting the requirements of safety extra-low voltage (SELV), one of the following must be true: 1. All inputs are SELV and floating, with the output also floating. 2. All inputs are SELV and grounded, with the

output also grounded. 3. Any non-SELV input must be provided with reinforced from any other hazardous voltages, including the ac mains, and must have a SELV reliability test performed on it in combination with the converters. Inputs must meet SELV requirements. If the input meets extra-low voltage (ELV) requirements, then the converter's output is considered ELV. The input to these units is to be provided with a maximum 10A normal blow fuse in the ungrounded lead. APA06G05(E-6) and APA6F05(E-6) need 15A fuse.
Mechanical Considerations
Thermal Performance APA06 series will derate at 55C under the condition of 200LFM. In order to maintain efficient heat dissipation, the converters should be mounted parallel with the air-flow direction. Soldering APA06 series converters are compatible with standard wave soldering techniques. When wave soldering, the converter pins should be preheated for 20-30 seconds at 110 C, and wave soldered at 260C for less than 10 seconds. When hand soldering, the iron temperature should be maintained at 425C and applied to the converter pins for less than 5 seconds. Longer exposure can cause internal damage to the converter. Cleaning can be performed with cleaning solvent IPA or with water.
