Product Highlights
EcoSmart
®
- Energy Efficient
Energy efficient over entire load range
No-load consumption below 100 mW at 265 VAC
Up to 750 mW standby output power for 1 W input at 230 VAC
High Design Flexibility for Low System Cost
Multi-mode PWM control maximizes efficiency at all loads
132 kHz operation reduces transformer and power supply size
66 kHz option for highest efficiency requirements
Accurate programmable current limit
Optimized line feed-forward for line ripple rejection
Frequency jittering reduces EMI filter cost
Fully integrated soft-start for minimum startup stress
725 V rated MOSFET
Simplifies meeting design derating requirements
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

-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.
