Application Information 6.1 Input and Output Impedance The POL converter should be connected to the DC power source via low impedance. In many applications, the inductance associated with the distribution from the power source to the input of the converter can affect the stability of the converter. Internally, the converter includes 4.7μF (low ESR ceramics) of input capacitance which eliminates the need for external input capacitance. However, if the distribution of the input voltage to the POL converter contains high inductance, it is recommended to add a 100μF decoupling capacitor placed as close as possible to the converter input pins. A low-ESR tantalum or POS capacitor connected across the input pins help ensuring stability of the POL converter and reduce input ripple voltage. A 22μF ceramic output capacitor is recommended to improve output ripple and dynamic response. It is important to keep low resistance and low inductance of PCB traces for connecting load to the output pins of the converter in order to maintain good load regulation. 6.2 Output Voltage Programming The output voltage can be programmed from 0.59V to 5.1V by connecting an external resistor RTRIM between TRIM pin (Pin 5) and GND pin (Pin 3), as shown in Figure 12. Figure 12. Programming Output Voltage With A Resistor The trim resistor RTRIM for a desired output voltage can be calculated using the following equation: , 591 . 0 182 . 1 OUT TRIM V R kΩ VIN GND ON/OFF VOUT 3 2 4 1 TRIM 5 Rload RTRIM YEV09T03 |
