NOTES:
A. I
B. Since the output MOSFET is switching, it is difficult to isolate the switching current from the supply current at the DRAIN. An
C. BYPASS/MULTI-FUNCTIONAL pin is not intended for sourcing supply current to external circuitry.
D. To ensure correct current limit it is recommended that nominal 0.1 μF / 1 μF / 10 μF capacitors are used. In addition, the BP/M
E. For current limit at other di/dt values, refer to Figure 25.
F. TNY284 does not have an increased current limit value, but with a 10 μF BYPASS/MULTI-FUNCTIONAL pin capacitor the current
G. This parameter is derived from characterization.
H. This parameter is derived from the change in current limit measured at 1X and 4X of the di/dt shown in the I
