## **APPLICATIONS:** ~~ee~~ 

## **GENERAL DESCRIPTION:** 

The uPOL module is non-isolated dc-dc converters that can deliver up to 5A of output current. The PWM switching regulator, high frequency power inductor are integrated in one hybrid package. It only needs input/output capacitors and voltage dividing resistors. 

The module was forced PWM mode, through constant on-time control, the module offers a simpler control loop and faster transient response. Other features include remote enable function, internal soft-start, non-latching over current protection, power good, and input under voltage locked-out capability. 

The low profile and compact size package is suitable for automated assembly by standard surface mount equipment.

## **SAFETY CONSIDERATIONS:** 

Certain applications and/or safety agencies may require fuses at the inputs of power conversion components. Fuses should also be used when there is the possibility of sustained input voltage reversal which is not current limited. For greatest safety, we recommend a fast blow fuse installed in the ungrounded input supply line. The installer must observe all relevant safety standards and regulations. For safety agency approvals, install the converter in compliance with the end-user safety standard. 

## **INPUT AND OUTPUT CAPACITOR SELECTION:** 

The module should be connected to as low AC impedance source supply and a highly inductive source or line inductance can affect the stability of the module. Ceramic capacitor has a DC-Bias effect which has a strong influence on the final effective capacitance. Choose the right capacitor carefully in combination with considering its package size and voltage rating. Ensure that the input effective capacitance is at least 12μF and the output effective capacitance is at least 22μF. Following are some suggestion for the input and output capacitor suggestion.

**FEEDFORWARD CAPACITOR FOR LOAD TRANSIENT CONSIDERATIONS:** The MUN3CAD05-JF integrates the compensation components to achieve good stability and fast transient responses. In some applications, adding a maximum 100pF ceramic cap between VOUT and FB may further speed up the load transient responses and is thus recommended for applications with large load transient step requirements. 

## **PROGRAMMING OUTPUT VOLTAGE:** 

The output voltage can be programmed by the dividing resistor RFB_top (recommended 10k~200kohm) and RFB_bot (recommended 10k~200kohm), Assume RFB_top set 100 Kohm, the output voltage can be calculated as shown in Equation 1 and the resistance according to typical output voltage is shown in TABLE 1.

## **THERMAL CONSIDERATIONS:** 

All of thermal testing condition is complied with JEDEC EIJ/JESD 51 Standards. Therefore, the test board size is 30mm×30mm×1.6mm with 4 layers 2oz. The case temperature of module sensing point is shown as FIG.21 Then Rth(jchoke-a) is measured with the component mounted on an effective thermal conductivity test board on 0 LFM condition. The module is designed for using when the case temperature is below 110°C regardless the change of output current, input/output voltage or ambient temperature.

## **REFLOW PARAMETERS:** 

Lead-free soldering process is a standard of electronic products production. Solder alloys like Sn/Ag, Sn/Ag/Cu and Sn/Ag/Bi are used extensively to replace the traditional Sn/Pb alloy. Sn/Ag/Cu alloy (SAC) is recommended for this power module process. In the SAC alloy series, SAC305 is a very popular solder alloy containing 3% Ag and 0.5% Cu and easy to obtain. Figure 22 shows an example of the reflow profile diagram. Typically, the profile has three stages. During the initial stage from room temperature to 150°C, the ramp rate of temperature should not be more than 3°C/sec. The soak zone then occurs from 150°C to 200°C and should last for 60 to 120 seconds. Finally, keep at over 217°C for 60~150 seconds to melt the solder and make the peak temperature at the range from 255°C to 260°C (Do not exceed 30 sec). It is noted that the time of peak temperature should depend on the mass of the PCB board. The reflow profile is usually supported by the solder vendor and one should adopt it for optimization according to various solder type and various manufacturers’ formulae.
