Products Detail

The LinkSwitch-PL family enables a very small and low cost single-stage power factor corrected constant current driver for solid state lighting. Optimized for direct LED current sensing, the LinkSwitch-PL operates over a wide input voltage range delivering an output power of up to 16 W. The LinkSwitch-PL control algorithm provides flicker-free TRIAC dimming with minimal external components. Each device incorporates a 725 V rated power MOSFET, a novel discontinuous mode variable frequency variable on-time controller, frequency jitter, cycle-by-cycle current limit and hysteretic thermal shutdown in a monolithic 4-pin IC, available in SO-8C, eSOP-12, and eDIP-12 packages.

Key Features

Flicker-free phase-controlled TRIAC dimming, Single-stage power factor correction and accurate constant current output, Very low component count with small non-electrolytic bulk capacitor, Compact SO8, eSOP, and eDIP packages, Completely eliminates control loop compensation, Optimized for non-isolated flyback designs, Frequency jitter greatly reduces EMI filter size and costs, Low dissipation direct sensing of LED current, Cycle skipping regulation for abnormally low output power, 725 V integrated power MOSFET, Short-circuit, overload, open feedback and output overvoltage protection, Hysteretic thermal shutdown, Meets high-voltage creepage between DRAIN and all other pins, High power factor optimizes system lumen per input, Control algorithm balances switching and conduction losses over line and load to maintain optimum efficiency
