Week 1 Fyp 2 : Assign the circuit that i will use on the project

Circuit Schematic


ZXLD1374 Device description




  • The ZXLD1374 is an LED driver IC with an internal MOSFETs to drive high current LEDs. It is a multi-topology driver enabling it to efficiently control the current through series connected LED. The multi-topology enables it to operate in Buck, Boost and Buck-boost configurations. 
  • The 60V capability coupled with its multi-topology flexibility enables it to be used in a wide range of applications and drive up to 15 LEDs in series. Th
  • ZXLD1374 is a modified hysteretic controller using a patent pending control scheme providing high output current accuracy in all three modes of operation. High accuracy dimming is achieved through dc dimming and high frequency PWM dimming. 
  • The ZXLD1374 uses two pins for fault diagnosis. A flag output highlights a fault presence, while the multi-level status pin gives further information on the specific fault.
