VPN12AD1E-FU

TYPICAL PERFORMANCE CHARACTERISTICS: (40 VOUT)

Conditions: TA = 25 ºC, unless otherwise specified. Test Board Information: 75mm× 58mm×1.6mm, 2 layers 2Oz .

The output ripple and transient response measurement is short loop probing and 20MegHz bandwidth limited.

Cin = 10uF/50V/1210×2, Cout = 10uF/50V/1210x4
