Power Integrations LNK606 | Demoboard DER-265

Description

The LinkSwitch-II family of devices were developed to cost effectively replace all existing solutions in low-power charger and adapter applications. Its core controller is optimized for CV/CC charging applications with minimal external parts count and very tight control of both the output voltage and current, without the use of an optocoupler. The LinkSwitch- II has an integrated 700 V switching MOSFET and ON/OFF control function which together deliver high efficiency under all load conditions and low no-load energy consumption. Both the operating efficiency and no-load performance exceed all current international energy efficiency standards.

Features

• Control concept provides very low cost, low part-count solution
• Primary-side control eliminates secondary-side control and optocoupler
• Provides ±5% constant voltage (CV) and ±10% constant current (CC) accuracy including output cable drop compensation for 0.35  cable
• Over-temperature protection – tight tolerance (±5%) with hysteretic recovery for safe PCB temperatures under all conditions
• Auto-restart output short-circuit and open-loop protection
• Extended pin creepage distance for reliable operation in humid environments; >3.2 mm at package
• EcoSmart™ – Easily meets all current international energy efficiency standards – China (CECP) / CEC / ENERGY STAR 2 / EU CoC
• No-load consumption <150 mW at 230 VAC
• Ultra-low leakage current: <5 A at 265 VAC input (no Y capacitor required)
• Design easily passes EN550022 and CISPR-22 Class B EMI testing with >6 dB margin

Typical applications

• Low-cost Charger or Adapter
