APPLICATION NOTES
Recommended Input & Output Capacitors
Although these converters will work without external capacitors, they are necessary in order to guarantee the full parametric performance over the full line and load range. All
parts have been tested and characterized using the following values and test circuit.
Input Voltage C
IN Output Voltage COUT
5V, 12V 100µF, 25V (0.25 at 100kHz) 3.3V, 5V 220µF, 16V (0.12 at 100kHz)
24V, 48V 10µF, 100V (1.5 at 100kHz) 12V, 15V 100µF, 25V (0.25 at 100kHz)
Test circuit
Reflected Ripple Current Measurement
C1 = 220µF, ESR < 0.1Ω at 100kHz
