NOTES:
1. For specifications with negative values, a negative temperature coefficient corresponds to an increase in
magnitude with increasing temperature, and a positive temperature coefficient corresponds to a decrease in
magnitude with increasing temperature.
2. It is possible to start up and operate TOPSwitchat DRAIN voltages well below 36 V. Refer to the "Low Input
Voltage" Specification section for details.
3. This section specifies only parameters affected by low input voltage operation (Drain Voltages less than 36 V). All
other parameters remain unchanged.
4. For low input voltage applications, the primary peak current could be set to a lower value than the current limit to
increase efficiency. Refer to the Output Characteristics graph (Drain Current vs. Drain Voltage). The voltage
across the transformer primary during the ON time is the difference between the input voltage and the drain
voltage (V
DS(ON)
).
For example, if the input voltage is 16 VDC and a TOP104 (3.3A minimum current limit) is used at a primary peak
current of 1A. Then the (V
DS(ON)
) is 3 V at 100
°
C and the energizing voltage across the transformer primary is
13 V.
