LNK454/456-458/460

Absolute Maximum Ratings^(1,4)

Notes:

DRAIN Pin Peak Current: LNK454................. 400 mA (750 mA)

LNK456................850 mA (1450 mA)

1. All voltages referenced to SOURCE, T_A= 25 °C.

2. Normally limited by internal circuitry.

3. 1/16 in. from case for 5 seconds.

LNK457............. 1350 mA (2000 mA)

LNK458..............1750 mA (2650 mA)

4. The Absolute Maximum Ratings speciﬁed may be applied,

one at a time without causing permanent damage to the

product. Exposure to Absolute Maximum Ratings for

extended periods of time may affect product reliability.

LNK460..............2700 mA (5100 mA)

DRAIN Pin Voltage ………………………............. -0.3 V to 725 V

FEEDBACK Pin Voltage ……………………… ............ -0.3 to 9 V

BYPASS Pin Voltage ………………………................. -0.3 to 9 V

Lead Temperature⁽³⁾................................................................260 °C

Storage Temperature …………………................... -65 to 150 °C

Operating Junction Temperature⁽²⁾.........................-40 to 150 °C
