Microchip Technology HV96001 LED Driver Evaluation Board

Microchip Technology HV96001 LED Driver Evaluation Board is used to evaluate and demonstrate the HV96001 LED driver from Microchip Technology. The flyback converter has implemented an active Power Factor Correction (PFC) control algorithm in the primary side by a PIC controller that commands the switching sequence. This allows the input current to follow the input voltage envelope.

Features

  • Linear (analog) dimming with a wide range of the amplitude control of the LED current
  • PWM (digital) dimming dims down to 0.01% and lower, with PWM pulse width down to 150ns
  • Flyback converter control with automatic output voltage adjustment for maintaining high system efficiency
  • Boost converter with near-zero output voltage ripple for ripple-free LED current
  • VDD internal regulator with 60V input voltage capability/5V output voltage, 10mA drive for supplying external loads
  • Fault recovery with auto-retry delay
  • Undervoltage detection of VDD voltage and supply voltage (flyback output voltage)
  • Overvoltage detection of the LED load voltage (boost output voltage)
  • Overcurrent detection of the load switch current
  • Stuck-at-zero detection of the DIM input signal
