FORWARD Pin Resistor
A 47 Ω, 5% resistor is recommended to ensure sufficient IC supply
current. A higher or lower resistor value should not be used as it can
affect device operation such as the timing of the synchronous rectifier
drive. Figures 8, 9, 10 and 11 below show examples of unacceptable
and acceptable FORWARD pin voltage waveforms. V
D is forward
voltage drop across the SR FET.
Figure 8. Unacceptable FORWARD Pin Waveform After Handshake with
SR FET Conduction During Flyback Cycle.
Figure 9. Acceptable FORWARD Pin Waveform After Handshake with
SR FET Conduction During Flyback Cycle.
Figure 10. Unacceptable FORWARD Pin Waveform before Handshake with Body
Diode Conduction During Flyback Cycle.
Note:
If t
1 + t2 = 1.5 ms ± 50 ns, the controller may fail the handshake and
trigger a primary bias winding OVP latch-off.
