Product Overview

ISL78171EVAL1Z evaluation board is used to evaluate the ISL78171 6-channel, 50mA automotive LED driver with ultra-high dimming ratio and phase shift control. This board is populated with 60 LEDs in 6P10S (six parallel strings, each string consisting of 10 LEDs in series) configuration to simplify evaluation and testing. The device can function with or without an I²C controller. If it is required to use I²C control for the ISL78171EVAL1Z board, use a generic I²C interface adapter (not supplied with the evaluation board kit) for the purpose of communication. Application includes infotainment display LED backlighting, LCD monitor LED backlighting, field sequential RGB LED backlighting.
  • Input voltage range from 4.5V to 26.5V
  • Output voltage is 32V typical and 40V maximum
  • LED string current is 20mA typical
  • Board dimension is 140.33mm x 64.77mm
  • Integrated 40V boost converter, 6 precision current sinks, up to 50mA each
  • Current matching is ±0.7% typical
  • Dimming modes are DC, internal PWM, direct PWM, DC + Int/Dir PWM
  • Phase shift control for internal PWM dimming
  • 600kHz/800kHz/1.2MHz I2C selectable switching frequency
  • Dynamic headroom control
