Both products incorporate multiple protection features to prevent damage during a fault condition. An internal soft-start circuit prevents a high inrush current during startup, and thermal shutdown protection shields the IC from thermal damage. Both devices monitor the LED string condition for open or shorts and automatically disable any faulty current sinks.Designers will benefit from smaller PCB footprints and lower BOM costs due to the high frequency operation of the boost converter. The addition of an external resistor allows for frequencies up to 1MHz. The device can be PWM modulated over a wide frequency range from 20Hz to 20kHz to provide a high contrast ratio. In addition, the lower external component count will enhance system reliability. No additional external circuitry is required to implement advanced functions such as open and short LED protection and high contrast PWM dimming.
