1. The RP40 series required a minimum 10% loading on the output to maintain specified regulation. Operation under no-load condition will not damage
these devices, however they may not meet all listed specification.
2. BELLCORE TR-NWT-000332. Case l: 50% Stress, Temperature at 40C (Ground fixed and controlled environment).
3. Simulated source impedance of 12uH. 12uH inductor in series with +Vin.
4. Maximum value at nominal input voltage and full load of standard type.
5. Typical value at nominal input voltage and full load.
6. Test by minimum Vin and constant resistor load.
7. The ON/OFF control pin voltage is referenced to negative input
8. Cross regulation:
Dual output--Asymmetrical load 25% to 100% full load
Triple output 3.3V / 5V 100% load and one of auxiliary 100% load, other
auxiliary load change from 25% to 100% load
9. See application notes for EMI-filtering.

1. The unit is capable of external synchronization from
an independent time base with a switching rate
between 200kHz and 215 kHz.
2. The amplitude of the synchronizing pulse train is
TTL compatible.
3. The duty cycle of the CLK should be 20% high and
80% low.
4. Synchronization is referenced to negative input
(Vin).
