Notes
1 Measurement Bandwidth: 20 MHz; Measured with 1 µF ceramic and a
330 µF (470 µF for 12 V output model) aluminum or solid tantalum
capacitor across the output terminals.
2 Di/dt = 1 A/µs; ∆Iout = ±25% Iout (max); Vin = Vnom; Iout = Inom. Tested
with a 1 µF ceramic and a 330 µF (470 µF for 12 V output model)
aluminum electrolytic capacitor across the output.
3 External input fusing required. Use a fast acting fuse: 40 A (24 V model),
15 A (48 V, 350 W model).
4 Iout = Iout (max) Measured with the input capacitor, Cbypass = 330 µF,
and 6 µH inductor in series with the power source. Frequencies
>100 kHz.
5 Signal line assumed <3 m in length.
6 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand-alone product.
7 Negative remote ON/OFF option also available. Add suffix ‘-R’ to part
number, for example see part numbering system.
8 With the enable signal asserted, this is the time from when the input
current reaches 10 % of the final steady state value until the output
voltage reaches 10 % of the nominal output value. Start-up into resistive
load.
9 With Vin > Vin (min.) applied for a minimum of 1 second, this is the time
from when the primary ON/OFF signal is activated until the output
voltage reaches 10 % of the nominal output voltage.
10 Minimum effective ESR is 1 mΩ. Minimum phase margin is 35º.
11 Measured per ETSI 300 132-2 Section 4.7.2.
12 From 10% to 90% of Vout (nom). Full resistive load. 1 µF ceramic and
330 µF (470 µF for 12 V model) electrolytic capacitors across the output.
RoHS Compliance (18)
Y = Non Pb-free (RoHS 5/6 compliant)

Notes Contd.
10 Minimum effective ESR is 1 mΩ. Minimum phase margin is 35º.
11 Measured per ETSI 300 132-2 Section 4.7.2.
12 From 10% to 90% of Vout (nom). Full resistive load. 1 µF ceramic and
330 µF (470 µF for 12 V model) electrolytic capacitors across the output.
13 Converter guaranteed ON for positive option.
14 Maximum driver leakage to insure converter is ON.
15 Converter guaranteed OFF for positive option.
16 Driver sink current @ Vrc ≤ 1.2 V.
17 0.40 in height option is not available on the 12 V output model.
18 The’Y’ suffix indicates that these parts are TSE ToHS 5/6 (non-Pb-free)
compliant
