Extensive Protection Features
⢠Auto-restart limits power delivery to <3% during overload faults
⢠Output short-circuit protection (SCP)
⢠Output over-current protection (OCP)
⢠Output overload protection (OPP)
⢠Output overvoltage protection (OVP)
⢠User programmable for hysteretic/latching shutdown
⢠Simple fast AC reset
⢠Primary or secondary sensed
⢠Line undervoltage (UV) detection prevents turn-off glitches
⢠Line overvoltage (OV) shutdown extends line surge withstand
⢠Accurate thermal shutdown with large hysteresis (OTP)
Advanced Package Options
⢠eDIPâ¢-12 package:
⢠Low profile horizontal orientation for ultra-slim designs
⢠Heat transfer to both PCB and heat sink
⢠Optional external heat sink provides thermal impedance
equivalent to a TO-220
⢠eSIP®-7C package:
⢠Vertical orientation for minimum PCB footprint
⢠Simple heat sink mounting using clip provides thermal
impedance equivalent to a TO-220
⢠Extended creepage to DRAIN pin
⢠Heat sink is connected to SOURCE for low EMI
Description
TOPSwitch-JX cost effectively incorporates a 725 V power
MOSFET, high voltage switched current source, multi-mode
PWM control, oscillator, thermal shutdown circuit, fault
protection and other control circuitry onto a monolithic device.
