NOTES:
I
S1 is an accurate estimate of device controller current consumption at no-load, since operating frequency is so low under these
conditions. Total device consumption at no-load is the sum of I
S1 and IDSS2.
Since the output MOSFET is switching, it is difcult to isolate the switching current from the supply current at the DRAIN. An
alternative is to measure the BP/M pin current at 6.1 V.
BP/M pin is not intended for sourcing supply current to external circuitry.
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
capacitor value tolerance should be equal or better than indicated below across the ambient temperature range of the target
application. The minimum and maximum capacitor values are guaranteed by characterization.
For current limit at other di/dt values, refer to Figure 23.
TNY274 does not set an increased current limit value, but with a 10 μF BP/M pin capacitor the current limit is the same as with a
1 μF BP/M pin capacitor (reduced current limit value).
This parameter is derived from characterization.
This parameter is derived from the change in current limit measured at 1X and 4X of the di/dt shown in the I
LIMIT specication.
I
DSS1 is the worst case OFF state leakage specication at 80% of BVDSS and maximum operating junction temperature. IDSS2 is a
typical specication under worst case application conditions (rectied 265 VAC) for no-load consumption calculations.
Breakdown voltage may be checked against minimum BV
DSS specication by ramping the DRAIN pin voltage up to but not
exceeding minimum BV
DSS.
Auto-restart on time has the same temperature characteristics as the oscillator (inversely proportional to frequency).
