DESCRIPTION

· TOPSwitch™-JX integrates a 725 V power MOSFET, high-voltage switched current source, multi-mode PWM control, oscillator, thermal shutdown circuit, fault protection, and other control circuitry into a monolithic device.

FEATURES

· EcoSmart™ technology ensures energy efficiency across the entire load range.
· 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 and optimized line feed-forward for line ripple rejection.
· Frequency jittering reduces EMI filter cost.
· Fully integrated soft-start for minimum start-up stress.
· Extensive protection features including auto-restart, output short-circuit, over-current, overload, overvoltage protection, and thermal shutdown.
· Advanced package options: eDIP™-12, eSIP™-7C, and eSOP™-12 for various power output capabilities and thermal management.
