2. Input power :
Pin = Vin x Iin
PRELIMINARY
Isolated DC-DC Converters
CHA2 Series -- 2Watt
Vin：Input voltage
Iin：Input current
3. Output power :
Pout = Vout x Iout
4. Efficiency :
Vout：Output voltage
Iout：Output current
Efficiency = ^{Pout x100%}
Pin
5. Voltage accuracy:
Pout: Output power
Pin: Input power
│Vout-Vout(nominal)│ _x100%
Vout
Vout：Output voltage
Vout(nominal)：Nominal output voltage
6. Line regulation: (1) Wide input voltage range and regulated output voltage series.
│Vout(LL)-Vout(HL)│ _x100%
Vout(LL)
LL: Low Line input voltage
HL: High Line input voltage
(2) Narrow input voltage range（±10%）and unregulated output voltage series.
Line regulation= ^ΔVout
ΔVin
ΔVout = ^{Vout(+10%)-Vout(-10%) x100%}
Vout
Vout(+10%)：Output voltage at Vin = 1.1xVin(nominal)&full load
Vout(-10%)：Output voltage at Vin = 0.9xVin(nominal)&full load
Vout：Output voltage at Vin = Vin(nominal)&full load
