Note : 2.Tlow=0°CV, T high=+70°C 3.Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible. 4.If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents (≤300mA) and high driver currents (≥30mA), it may take up to 2.0µs for it to come out of saturation. This condition will shorten the off time at frequencies≥30kHz, and is magnified at high temperatures. This condition does not occur with a Darlington configuration, since the output switch cannot saturate. If a non-Darlington configuration is used, the following output drive condition is recommended : IC output ≥ 10 Forced β of output switch : IC driver - 7.0mA* * The 100Ω resistor in the emitter of the driver device requires about 7.0mA before the output switch conducts.

VF = Forward voltage drop of the output rectifier. The following power supply characteristics must be chosen : Vin - Nominal input voltage. R2 Vout - Desired output voltage, IVoutI = 1.25 1 + R1 Iout - Desired output current. f min - Minimum desired output switching frequency at the selected values of Vin and Io. Vripple(pp) - Desired peak-to-peak output ripple voltage. In practice, the calculated capacitor value will need to be increased due to its equivalent series resistance and board layout. The ripple voltage should be kept to a low value since it will directly affect the line and load regulation. Copyright ANPEC Electronics Corp. Rev.
