powerint公司的13.5w隔离的可调光的pfc led驱动器采用linkswitchtm-ph系列的lnk406eg器件,输入电压185vac到265vac,输出36v/425ma,可用于par30 / par38反射灯.本文介绍了linkswitch-ph系列led驱动器主要特性,框图,7w和14w led驱动器电路图以及用于par30 / par38的13.5w led驱动器参考设计der314主要特性和指标,电路图和材料清单,变压器电路图和pcb布局图.
the linkswitch-ph dramatically simplifies implementation of led drivers requiring long lifetime, high efficiency, pf >0.9, and triac dimming capability (lnk403-409). the single-stage combined power factor and constant-current controller eliminates a switching stage and the electrolytic bulk capacitor. the advanced primary-side control used by the linkswitch-ph device provides accurate constant current control while eliminating the need for an optocoupler and current sensing circuits.
linkswitch-ph incorporates a 725 v power fet, a continuous-mode pwm controller, a high voltage switched current source for self biasing, frequency jittering, protection circuitry including cycle-by-cycle current limit and hysteretic thermal shutdown.

the document describes an isolated high power factor (pf) triac dimmable led driver designed to drive a nominal led string voltage of 36 v at 425 ma from an input voltage range of 185 vac to 265 vac. the led driver utilizes the lnk406eg from the linkswitch-ph family of ics.
key goals for this design were:
lowest cost
small size
efficiency
demonstration of (optional) thermal fold back (output current reduces above temperature threshold)
the topology used is a single-stage power factor corrected flyback that meets high efficiency, high power factor, low thd, isolation, low component count, and stringent space requirements for this design.
high power factor and low thd is achieved by employing the linkswitch-ph ic which also provides a sophisticated range of protection features including auto-restart for open control loop and output short-circuit conditions. line overvoltage provides extended line fault and surge withstand, and accurate hysteretic thermal shutdown that ensures safe average pcb temperatures under all conditions.
this document contains the led driver specification, schematic, pcb diagram, bill of materials, transformer documentation and typical performance characteristics.
参考设计der314主要特性:
high efficiency, ≥87% at 230 vac
low cost
single-stage converter
single sided pcb
low component count
enhanced user experience
flicker free, fast monotonic start-up (<300 ms) – no perceptible delay
broad dimmer compatibility
flicker-free
tested with common types from australia, china, korea and germany
integrated protection and reliability features
output open circuit / output short-circuit protected with auto-recovery
line input overvoltage shutdown extends voltage withstand during line faults
auto-recovering thermal shutdown with large hysteresis protects both components and
