Power Integrations, LED Driver IC, Minimum of 50 V, eDIP-12 LNK458VG / 1235510

LinkSwitch-PL series LED Driver AC-DC Converters. A range of off-line AC-DC converters from Power Integrations designed for use as LED drivers in solid-state lighting applications. The devices feature single-stage PFC and constant current control for non-isolated applications and a control algorithm which provides flicker-free TRIAC dimming with minimal external components. These 4-pin monolithic ICs integrate a high-voltage power MOSFET, a novel discontinuous-mode variable frequency variable on-time controller, frequency jitter, cycle-by-cycle current limit and hysteretic thermal shutdown circuitry. Optimized for non-isolated flyback designs Single-stage power factor correction and accurate constant current output Flicker-free phase-controlled TRIAC dimming Very low component count with small non-electrolytic bulk capacitor for compact replacement lamp designs Complete elimination of control loop compensation Frequency jitter greatly reduces EMI filter size and costs Low dissipation direct sensing of LED current Short-circuit, overload, open feedback and output overvoltage protection Hysteretic thermal shutdown Meets high-voltage creepage between DRAIN and all other pins both on PCB and at package Compact SO8, eSOP12 and eDIP12 packages
