NOTES:
A. This parameter is derived from characterization.
B. Output frequency specification applies to low line input voltage in the final application. The controller is designed to reduce output
frequency by approximately 20% at high line input voltages to balance low line and high line maximum output power.
C. The auto-restart on-time/off-time is increased by 20% from low to high line voltage input (85 VAC to 265 VAC).
D. IBPSC is the current that can be supplied from the BYPASS pin at 5.85 V when in normal switching mode of operation to power an
optional external circuit. The current will be supplied from the Drain via the internal BYPASS pin voltage regulator. When calculat-
ing the power consumption the IBPSC (84 mA max) and the drain voltage has to be taken into account. More current can be
sourced during Power-Down mode – see Note F.
E. IBPSC(PD) is the current that can be supplied from the BYPASS pin at 4 V when in Power-Down mode to power an optional external
circuit. The current will be supplied from the Drain via the internal BYPASS pin voltage regulator. Lower current is available during
normal operation - see Note E. If the external circuit requires current in excess of IBP(PD) in Power-Down mode, it must be supplied
from an external source such as a bias winding. The IBP(PD) current adds to power supply power consumption during Power-Down
mode – for example at 230 VAC (325 VDC rectified DC rail voltage) the power consumption with be 325 × IBP(PD)
.
F. LinkZero-AX shuts down if the current into the BYPASS pin reaches ISD at the BPSHUNT voltage.
