1. Maximum output power not to exceed 75W total for 5/3.3V version (15A).
2. The sum of output currents not to exceed 15amps for 5/3.3V (19A max for 3.3/2.5V).
3. Any output loading ratio within the maximum specified limits is possible.
Single Output

Notes
1. 20MHz bandwidth. An external 2.2mf ceramic capacitor is
recommended to be placed from +V out to -V out.
2. Requires a 2.2mf, 100V film capacitor connected between +V in
and -V in to meet FCC class A and ETS300-386-1 requirements
for conducted noise.
3. All specifications are typical at nominal line, full load, and 25C
unless otherwise noted.
4. All specifications subject to change without notice. Mechanical
drawings are for reference only.
5. Please refer to the Technical Reference Notes for more
information.
