... Figure 1. Extremely high efficiency power conversion is achieved through the use of synchronous rectification and drive techniques. Essentially, the powerful VPOL15A-5-SIP series topology is based on a non-isolated synchronous buck converter. The control loop is optimized for unconditional stability, fast transient response and a very tight line and load regulation ...

... The remote on/off input feature to turn the converter on that can standard. The VPOL15A-5-SIP series converters are turned on if the remote on/off pin is high, or left open or floating. Setting the pin low will turn the converter ‘Off’. The signal level of the remote on/off input is defined with respect to ground. If not using the remote on/off pin, leave the pin open (module will be on). The part number suffix “ ...

... Layout Design Challenges. In optimizing thermal design the PCB is utilized as a heat sink. Also some heat is transferred from the VPOL15A-5-SIP module to the main board through connecting pins. The system designer or the end user must ensure that other components and metal in the vicinity of the ...

... The thermal data presented is based on measurements taken in a set-up as shown in Figure 6. Figures represent the test data. Note that the airflow is parallel to the long axis of the module as shown in Figure 6 for the VPOL15A-5-SIP. The temperature at either location should not exceed 110 °C. The output 76.2(3.0) power of the module should not exceed the rated power for the module (VO, set x IO, max) ...

... PART NUMBER: VPOL15A-5-SIP 7.6 Input Capacitance at the Power Module The VPOL15A-5-SIP converters must be connected to a low AC source impedance void problems with loop stability source inductance should be low. Also, the input capacitors should be placed close to the converter input pins to de-couple distribution inductance. However, the external input capacitors are chosen for suitable ripple handling capability ...

... PART NUMBER: VPOL15A-5-SIP 7.9 VPOL15A-5-SIP Series Output Voltage Adustment. The output voltage of the VPOL15A-5-SIP can be adjusted in the range 0.9V to 3.63V by connecting a single resistor on the motherboard (shown as Rtrim) in Figure 14. When trim resistor is not connected the output voltage defaults to 0.75V +Vin +Vo Trim VPOL15A-5-SIP ...
