BUB20 Series -- 20 Watt
â â 6. Line regulation: (1) Wide input voltage range and regulated output voltage series.
âVout(LL)-Vout(HL)â x100%
Vout(LL)
LL: Low Line input voltage
HL: High Line input voltage
(2) Narrow input voltage rangeï¼Â±10%ï¼and unregulated output voltage series.
Line regulation=
ÎVout
ÎVin
ÎVout = Vout(+10%)-Vout(-10%) x100%
Vout
Vout(+10%)ï¼Output voltage at Vin = 1.1xVin(nominal)&full load
Vout(-10%)ï¼Output voltage at Vin = 0.9xVin(nominal)&full load
Voutï¼Output voltage at Vin = Vin(nominal)&full load
ÎVin = Vin(+10%)-Vin(-10%) x100%
Vin(nominal)
Vin(+10%)ï¼Input voltage = 1.1xVin(nominal)
Vin(-10%)ï¼Input voltage = 0.9xVin(nominal)
Vin(nominal)ï¼Nominal Input voltage
7. Load regulation :
âVout(FL)-Vout(NL)â x100%
Vout(FL)
Vout(FL): Output voltage at full load
Vout(NL): Output voltage at 25% full load or 10% full load
8. Ripple and Noise: as shown below. The bandwidth is 0-20MHz.
