on semi公司的ncl30001是能实现pfc和隔离ac/dc降压电源转换的高度集成控制器,非常适合功率在40w-150w间的led驱动器电源. ncl30001可配置成恒流驱动或固定输出驱动,可调整工作频率20 khz 到250 khz,主要用于led街灯照明,大功率led驱动器和建筑物led照明.本文介绍了ncl30001主要特性,方框图,典型应用电路以及高pfc的100v/450ma离线led驱动器指标和电路图.
the ncl30001 is a highly integrated controller for implementing power factor correction (pfc) and isolated step down ac−dc power conversion in a single stage, resulting in a lower cost and reduced part count solution. this controller is ideal for led driver power supplies with power requirements between 40 w and 150 w. the single stage is based on the flyback converter and it is designed to operate in continuous conduction (ccm).
the ncl30001 can be configured as constant current driver or a fixed output driver for two stage led lighting applications. in addition, the controller features a proprietary soft−skipto reduce acoustic noise at light loads. other features found in the ncl30001 include a high voltage startup circuit, voltage feedforward, brown out detector, internal overload timer, latch input and a high accuracy multiplier. the multi−function latch off pin can also be used to implement an overtemperature shutdown circuit.
ncl30001主要特性:
voltage feedforward improves loop response
frequency jittering reduces emi signature
roprietary soft−skip at light loads reduces acoustic noise
brown out detector
internal 160 ms fault timer
independent latch−off input facilitates implementation of overvoltage and overtemperature fault detectors
average current mode control (acmc), fixed frequency operation
high accuracy multiplier reduces input line harmonics
adjustable operating frequency from 20 khz to 250 khz
these devices are pb−free and are rohs compliant
ncl30001应用:
led street lights
low bay led lighting
high power led drivers
architectural led lighting

this design note (dn) is an extension to on semiconductor’s application note and8470/d and features a 100 volt max, 0.45 amp version of the off-line, ncl30001 based constant voltage, constant current (cvcc) led driver with inherent pfc described in that app note.
the original app note features a 50 volt max, constant current, 1 to 2 amp (current settable) led driver with multiple dimming capabilities and active power factor correction in a single continuous conduction mode (ccm) flyback converter stage. this dn presents a similar version that is suitable for driving series led strings up to 100 volts at a max current of up to about 600 millamps. this design is suitable for led strip lighting and fluorescent lamp replacements. the maximum voltage and output current can be adjusted via resistors r34 and r32 respectively. the detailed circuit operational description can be found in the original mentioned app note (and8470/d) and is essentially identical circuit-wise with the exception of the component changes that are indicated in the bom. the flyback transformer design for this dn was merely ratioed from the secondary winding on the original design to meet the new maximum voltage and current requirements. the primary winding, required inductance, and overall construction are essentially the same.
100v/450ma离线led驱动器主要特性:
single stage, isolated pfc converter for strip lighting and fluorescent tube replacements.
constant voltage, constant current output characteristic for led drive
dimming features including pulse width dimming to 3%
over current, over voltage and over temperature capabilities
typical efficiencies above 86%
