The ALT80600 is a multi-output LED driver for small-size LCD backlighting. It integrates a current-mode boost converter with internal power switch and four current sinks. The boost converter can drive up to 44 white LEDs, 11 LED per string, at 120 mA (VF = 3.3 V max). LED sinks can be paralleled together to achieve higher currents up to 480 mA. The ALT80600 operates from single power supply from 4.5 to 40 V; once started, it can continue to operate down to 3.9 V. This allows the part to withstand stop/start, cold crank, and load dump conditions encountered in automotive systems.
  • Wide input voltage range of 4.5 to 40 V for start/stop, cold crank, and load dump requirements
  • Fully integrated LED current sinks and boost converter with internal power MOSFET
  • Operate in Boost or SEPIC mode for flexible output
  • Drives up to 11 series white LED in 4 parallel strings, at up to 120 mA per string (VF = 3.3 V max).
  • Programmable boost switching frequency or sync externally from 200 kHz to 2.3 MHz
  • Clock-Out feature for internal switching frequency
  • Adjustable boost frequency dithering to reduce EMI
  • Advanced control allows minimum PWM on-time down to 0.3 µs, and avoids MLCC audible noises
  • LED contrast ratio: 15,000:1 at 200 Hz using PWM dimming alone, 150,000:1 when combining PWM and analog dimming
