Absolute Maximum Ratings(1,5)
DRAIN Pin Voltage..............................................-0.3 V to 700 V Notes:
Peak DRAIN Pin Current (LYT0002) .............. 200 mA (375 mA)(2) 1. All voltages referenced to SOURCE, TA = 25 °C.
Peak DRAIN Pin Current (LYT0004) .............. 400 mA (750 mA)(2) 2. The higher peak DRAIN current is allowed if the DRAIN
Peak DRAIN Pin Current (LYT0005) ............ 800 mA (1500 mA)(2)
to SOURCE voltage does not exceed 400 V.
Peak DRAIN Pin Current (LYT0006) .......... 1400 mA (2600 mA)(2) 3. Normally limited by internal circuitry.
FEEDBACK Pin Voltage..........................................-0.3 V to 9 V 4. 1/16 in. from case for 5 seconds.
FEEDBACK Pin Current................................................. 100 mA 5. Maximum ratings specified may be applied, one at a time,
BYPASS Pin Voltage...............................................-0.3 V to 9 V
