The Power Integrations TOPSwitch-JX series offers a single-package solution to cost-effective off-line AC-DC converter design. The devices integrate a high-voltage power MOSFET and switched current source, multi-mode PWM controller, oscillator and comprehensive protection plus control circuitry into a compact monolithic package. The range includes both through-hole and SMT mounted options and power ratings of up to 177W.

• Energy efficient over entire load range; no-load power <100 mW at 265 VAC
• Multi-mode PWM control maximizes efficiency at all loads
• Accurate programmable current limit
• Frequency jittering reduces EMI filter cost
• Fully integrated soft-start for minimum start-up stress
• 725V rated power MOSFET
• Auto-restart limits power delivery to <3% during overload faults
• Output over-voltage, over-current and short-circuit protection
• Accurate thermal shutdown with large hysteresis
Package Options:
• eDIP-12 package with low-profile horizontal orientation for ultra-slim designs
• eSIP-7C package with vertical orientation for minimum PCB footprint
• eSOP-12 low-profile SMT package for ultra-slim designs
