Specifications Contd.

Notes

1

Measured with 10 μF tantalum capacitor and 1 μF ceramic capacitor across

output.

2

di/dt = 0.1 A/1 μs, Vin = 48 Vdc, Tc = 25 °C, load change = 0.5 lo max. to 0.75 lo

max. and 0.75 lo max. to 0.5 lo max.

3

Units should be characterised within systems. External components required.

4
