HV9964 - CCM Boost LED Driver

Description

The HV9964 is a current mode control LED driver IC designed to control single switch PWM converters (boost or SEPIC) in a constant frequency mode.

Features

  • Switch-mode controller for single switch converters.
  • Boost.
  • SEPIC.
  • Current loop closed with sub-microsecond PWM dimming pulses supports PWM dimming >20kHz.
  • High PWM dimming ratio (>10,000:1).
  • Internal 40V linear regulator.
  • Internal ±2% voltage reference.
  • Programmable constant frequency operation.
  • Programmable slope compensation.
  • Programmable soft start.
  • 10V, +0.25A/-0.5A MOSFET gate drivers.
  • Hiccup mode protection for both sh.
