Notes and Conditions

Isolated floating opto coupler

input. Can use 3.3 V output

(secondary) or directly

use enable A or B (primary) to

turn on main 12 V output

Current flowing (into pin 14, out

of pin 13) to turn on 12 V output

Acceptable leakage current (into

pin 14, out of pin 13)

Converter is guaranteed on

when r/c voltage (pin 14 wrt to

pin 13) is equal to or greater

than Vil (min)

Maximum photodiode voltage drop

Series resistance between pin 14

and pin 13

Isolation of signal from primary

and from secondary circuits

according to EN60950 and UL60950

Two open collector outputs,

used to monitor the status of

-48 V_A and -48 V_B buses

respectively. Signal is active low,

when buses are ‘OK’

Minimum voltage required at the

input to IBC for A_OK# and

B_OK# to be okay

Sink current capability of each pin

Maximum leakage current in

open collector transistor when

pin is pulled to 3.3 V

Isolation of signal pins from

primary circuits according to

EN60950 and UL60950

Allows the 3.3 V to be trimmed

up and down

Connect trim pin to output return

to trim high, and to 3.3 Vout to

trim low. See Application Note 205

V/mA, current from pin

increases output voltage

See Application Note 205 for

further details
