SWITCHING WAVEFORMS
Notes:
1. Unless otherwise noted, test conditions are BAT = –60 V, V
2. Overload level is defined when THD = 1%.
3. Balance return signal is the signal generated at V
4. Not tested in production. This parameter is guaranteed by characterization or correlation to other tests.
5. These tests are performed with a longitudinal impedance of 90
6. This parameter is tested at 1 kHz in production. Performance at other frequencies is guaranteed by characterization.
7. When the SLIC is in the Anti-Sat 2 operating region, this parameter is degraded. The exact degradation depends on system
8. “Midpoint” is defined as the connection point between two 300
9. Fundamental and harmonics from 256 kHz switch regulator chopper are not included.
