## **GENERAL DESCRIPTION:** 

The uPOL module is non-isolated dc-dc converter that can deliver up to 3A of output current. The PWM switching regulator, high frequency power inductor are integrated in one hybrid package. It only needs input/output capacitors and one voltage dividing resistor to perform properly. 

The module has automatic operation with PWM mode and power saving mode according to loading, 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, input under voltage locked-out capability. 

The low profile and compact size package (3.0mm × 2.8mm x 1.5mm) is suitable for automated assembly by standard surface mount equipment. The uPOL module is Pb-free and RoHS compliance.

## ~~ee~~ **APPLICATIONS INFORMATION: (Cont.)** 

## **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 FILTERING:** 

The module should be connected to a source supply of low AC impedance and high inductance in which line inductance can affect the module stability. An input capacitor must be placed as near as possible to the input pin of the module so to minimize input ripple voltage and ensure module stability. 

## **OUTPUT FILTERING:** 

To reduce output ripple and improve the dynamic response as the step load changes, an additional capacitor at the output must be connected. Low ESR polymer and ceramic capacitors are recommended to improve the output ripple and dynamic response of the module. 

## **PROGRAMMING OUTPUT VOLTAGE:** 

The module has an internal 0.8V ± 1.5% reference voltage. The output voltage can be programmed by the dividing resistor (RFB_T and RFB_B). The output voltage can be calculated by Equation 1, resistor choice may be referred to TABLE 2.

## **Soft Startup Capacitor Selection** 

Leave SS pin floating for default 1ms soft-start time. For longer than 1ms soft-start time, connect a capacitance between the SS pin and the GND allows programming the startup slope of the output voltage. A constant current of 4 μ A charges the external capacitor. The capacitance required for a given soft startup time for the output voltage is given by Equation 2:

## **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 Figure 35. Then Rth(jchoke-a) is measured with the component mounted on an effective thermal conductivity test board on 0 LFM condition. The MUN12AD03-SEC modules are 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:** 

## **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 36 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 limit 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.
