Tested at 0-20 MHz
BW, with a 1 uF
ceramic capacitor and
a 10 uF Tantalum
capacitor at the
output.
Recommend to use
AVX TPS series
Tantalum capacitor as
min capacitor.
Test conditions: di/dt
= 0.1 A/uS, Vin=48 V,
with a 1 uF ceramic
capacioor and a Min
Capacitance of
Tantalum capacitor at
the output
