LED drivers

 

Moxie Devices’ solar charge controller

  • Compact microcontroller-based design. Circuit can be customised for various battery configurations as per required autonomy

  • Constant current regulation for the LED driver

  • Two-stage charging optimises battery performance

  • Integrated temperature compensation

  • Dimming option

  • LED indicators for charging status/low battery/fault conditions 

Meanwell’s HLG series

  • Universal AC input/full range (up to 305V AC)

  • Built-in active PFC function

  • Dimming option

  • LED driver with PFC function

  • Metallic cases

  • Various housings like IP65 and fully encapsulated IP67 protection arious housings like IP65 and fully encapsulated IP67 protection

GlacialPower’s RS series of constant current and constant voltage drivers

  • The output voltage of the two LED lights ranges from 12V DC to 57V DC. GP-RS45P delivers up to 48W, and

  • GP-RS60P up to 60W of power to the LED

  • Available with a 3-in-1 dimming (1-10V/PWM/resistor) function

  • Robust IP67-approved plastic housing protects the drivers from possible dust or water damage such as rusting

  • Double insulated wiring design ensures that if the wire is externally pulled, the strain relief bushing to the circuit board will not be exposed, preventing possible electricity leakage

  • Universal AC input 90 to 305V AC

ON Semiconductor’s NCL3008x series

  • Uses information on the primary side to precisely regulate the current in the secondary side, providing constant current for fly-back and non-isolated buck-boost topologies

  • The series provides best-in-class primary-side current regulation < ± 1% (typ), thus simplifying LED selection

  • Supports wide forward voltage (Vf), simplifying design and reducing engineering cost

  • Features high efficiency quasi-resonance switching with low EMI generation

  • User-controlled thermal current fold-back protecting LEDs from improper usage

Renesas Electronics’ R2A20134 LED driver 
  • Applies high-side step-down control so that low-cost MOSFETs can be used pplies high-side step-down control so that low-cost MOSFETs ca

  • Delivers power-conversion efficiencies as high as 92 per cent

  • Achieves a truly environment-friendly power factor of 0.9 or more

  • Accommodates various types of control circuits to provide design flexibility

  • Efficiency of 85 per cent or more

  • Total harmonic distortion [THD]: 20 per cent or less

Texas Instruments’ TPS92660
  • Its analogue or pulse width modulation (PWM) input signals can be used for brightness and colour adjustment after ROM programming

  • I2C and on-time programmable

  • ROM for trim of white CCT and lumen output eliminates need for binned LEDs

  • Accepts PWM or analogue dimming for brightness and colour adjustment

  • Integrated 3V ± 3 per cent voltage reference can be used for housekeeping circuits
