ΔVin=

Vin(+10%)-Vout(-

10%)

x 100%

Vin(nominal)

Vin(+10%): Input Voltage=1.1 x Vin(nominal)

Vin(-10%): Input Voltage=0.9 x Vin(nominal)

Vin(nominal): Nominal Input Voltage

7. Load Regulation:

| Vout(FL)-Vout(NL) | x 100%

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 0-2MHz

Output Ripple & Noise measurement test circuit: as shown below

9. Temperature Derating Curve: The DC/DC converter will operate over a wider temperature range if less power is drawn from the output and the

device is already running. The temperature derating curve shows the operating power-temperature range. As shown below.

10. Switching Frequency: The nominal operating frequency of the DC/DC converters.

11. Input to Output Isolation: The dielectric breakdown strength test between input and output circuits. This is the isolation voltage the device is

capable of withstanding for a specified time, usually 1 second or 1 minute.
