Notes

1

Measured as per recommended set-up. Cin = 270µF (20mΩ esr max,

Cout = 680µF (10mΩ esr max).

2

di/dt =

0.75 lo max. and 0.75 lo max. to 0.50 lo max.

3

External input fusing is recommended.

4

Measured with external filter. See Application Note 131 for details.

5

Uses external resistor from trim pin to output ground. Min value = 485Ω

for 5V model, 280Ω for 12V model. See Application Note 131 for details.

6

Signal line assumed <3m in length

7

This product is only for inclusion by professional installers within other

equipment and must not be operated as a stand alone product.

8

The standard unit with the suffix '-V' is for vertical mounting. To order a

unit with horizontal mounting, please add the suffix '-H' to the model

number, e.g. SIL15-05SADJ-H.

9

Power-up is the time from application of DC input to Power Good

enabled. Remote ON/OFF is from ON/OFF asserted high to power good

enabled.

3.3V and 12 Vin has an output of 0.9V to 5V. An external resistor adjusts

the output voltage.
