APPLICATION INFORMATIONS
1. Main Inductor
L =
h * ( VO - VP ) * VP2 / ( 4 * VO * PO * f )
Where,
h: Efficiency ( 0.95)
VO: DC Link Voltage
VP: Input Peak Voltage
PO: Output Power
f: Switching Frequency
2. Resistor for Current Sense
RS = 1.6 / ILP
Where,
ILP: Inductor Peak Current
3. Resistors for Multiplier
RML < 0.69 * RMU / ( VP – 0.69 )
Where,
RMU: Upper Resistor for Multiplier Input
RML: Lower Resistor for Multiplier Input
4. Resistors for Error Amplifier
REL = 2.5 * REU / ( VO - 2.5 )
Where,
REU: Upper Resistor for Error Amplifier Inverting Input
REL: Lower Resistor for Error Amplifier Inverting Input
