Description

Electronic Component Model: LNK564 is a LinkSwitch-TN IC chip specifically designed to replace all linear and capacitor-fed non-isolated power supplies in the under 360 mA output current range. It offers much higher performance and energy efficiency while maintaining an equal system cost.

Specifications and features

- Cost Effective Linear/Cap Dropper Replacement - Lowest cost and component count buck converter solution - Fully integrated auto-restart for short-circuit and open loop fault protection - LNK302 uses a simplified controller without auto-restart for very low system cost - 66 kHz operation with accurate current limit - Tight tolerances and negligible temperature variation - High breakdown voltage of 700 V provides excellent input surge withstand - Frequency jittering dramatically reduces EMI (~10 dB) - High thermal shutdown temperature (+135 °C minimum)

Application Scenarios

LNK564 is commonly used in appliances, timers, LED drivers, and industrial controls.

Comparison

- Much higher performance over discrete buck and passive solutions - Supports buck, buck-boost, and flyback topologies - System level thermal overload, output short-circuit, and open control loop protection - Excellent line and load regulation - High bandwidth provides fast turn-on with no overshoot - Current limit operation rejects line ripple - Universal input voltage range (85 VAC to 265 VAC) - Built-in current limit and hysteretic thermal protection - Higher efficiency than passive solutions - Higher power factor than capacitor-fed solutions - Entirely manufacturable in SMD - EcoSmart® – Extremely energy efficient, meets California Energy Commission (CEC), Energy Star, and EU requirements

- No disadvantages mentioned in the product description.
