Tested at 0-20 MHz
BW, with a 1 uF
ceramic capacitor and
a Tantalum capacitor
(refer to the min.
output capacitance
below for each output)
at the output.
Recommend to use
AVX TPS series
Tantalum capacitor as
the min capacitor

Test conditions: di/dt
= 0.1 A/uS, Vin=48 V,
with a 1uF ceramic
capacitor and a
Tantalum capacitor
(refer to the min.
output capacitance
above for each
output) at the output.
Note: All specifications are typical at nominal input, full load at 25 °C unless otherwise stated.
