Application Information

1. Main Inductor

L = η × (VO −VP ) ×VP2 /(4VO × PO × f )

Where,

η: Efficiency (0.95)

VO: DC Link Voltage

VP: Input Peak Voltage

PO: Output Power

f: Switching Frequency

2. Resistor for Current Sense

RS = 1.75/ILP

Where,

ILP: Inductor Peak Current

3. Resistor for Multiplier

RML<0.69 x RMU / (VP– 0.69)

Where,

RMU: Under Resistor for Multiplier Input

RML: Lower Resistor for Multiplier Input

4. Resistor for Error Amplifier

REL = 2.5 x REU / (VO – 2.5)

Where,

REU: Under Resistor for Error Amplifier Inverting Input

REL: Lower Resistor for Error Amplifier Inverting Input
