powerint公司的linkswitchtm-ph系列是led驱动器系列,单级pfc,初级恒流控制,可选择triac调光/不调光,不需要光耦和电流检测电路.器件集成了725v功率fet,连续模式pwm控制器,用于自偏压的高压开关电流源,频率抖动和保护电路,从大局出发大大简化了离线led驱动器,主要用于离线led驱动器.本文介绍了linkswitch-ph系列产品亮点,方框图,14w和7w led驱动电路图,以及采用lnk419eg的40.5w街灯led照明电路参考设计主要特性和指标,电路图,材料清单和pcb元件布局图.
the linkswitch-ph dramatically simplifies implementation of led drivers requiring long lifetime, high efficiency, pf >0.9, and triac dimming capability (lnk403-410). 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.
linkswitch-ph系列产品亮点:
dramatically simplifies off-line led drivers
• single-stage combination of power factor correction and accurate constant-current (cc) output
• enables very long lifetime designs (no electrolytic capacitors)
• eliminates optocoupler and all secondary current control circuitry
• eliminates control loop compensation circuitry
• simple primary-side pwm dimming interface
• universal input voltage range
• lnk403-410 optimized for flicker-free triac dimming ecosmart™ – energy efficient
• single-stage pfc combined with output cc control
• greatly increases efficiency, >90% achievable
• reduces component count
• no current sense resistors
• low standby power remote on/off feature (88% at 230 vac
>87% at 120 vac
<2% line and load regulation
<5% iout tolerance
low cost, low component count and small, single-sided printed circuit board
frequency jitter allows smaller, lower cost emi filter
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 printed circuit board
iec 61000-4-5, iec 61000-3-2 class c, and en55015 b conducted emi compliant
