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 (CC) 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
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 (>0.9 at 115 VAC / 230 VAC)
Low THD (<15% at 230 VAC, <10% at 115 VAC)

Application scenarios

Solid state lighting
LED replacement lamps
non-isolated applications
