MAX20056B Integrated, 6-Channel High-Brightness LED Driver with Very Wide PWM Dimming Ratio and Phase Shifting for Automotive Displays General Description Benefits and Features The MAX20056B is a 6-channel LED driver that Robust with Respect to EMC and Automotive Battery integrates a DC-DC switching boost/SEPIC controller and Transients six 120mA current sinks. A current-mode switching DC-DC Wide 4.5V to 42V Input Operating Range Powers controller provides the necessary voltage to the strings of HB LEDs for Medium-to-Large-Sized LCD Displays HB LEDs. in Automotive and Display Backlight Applications Withstands Automotive Load-Dump Events Up to 52V An internal current-mode switching DC-DC controller Integrated Spread Spectrum supports boost, SEPIC, or coupled-inductor buck-boost topologies and operates in a programmable frequency Spread-Spectrum Mode Reduces Emission at the range between 400kHz and 2.2MHz. Current-mode control Switching Frequency and its Harmonics provides fast response and simplifies loop compensation. EMI Reduction Features Include Spread-Spectrum An adaptive output-voltage-adjustment scheme minimizes Modulation (6% of the Switching Frequency Set power dissipation in the LED current sinks. by a Resistor Connected Between RT and SGND) An external resistor sets the channel currents to the Phase-Shift Dimming of LED Strings same value in the range of 20mA to 120mA. The Reduced Input and Output Ripple/Audible Noise device features logic-controlled pulse-width modulation Wide Contrast Ratio Ideal for High-Quality TFT and (PWM) dimming with minimum pulse widths as low as Head-Up Displays 500ns, and either phase-shifted LED strings or standard PWM Dimming Ratio of 10,000:1 at 200Hz dimming control. When phase shifting is enabled, each Robust with Respect to Temperature and Fault string is turned on at a different time, reducing the input Conditions and output ripple as well as audible noise. With phase LED-Open/Short Detection shifting disabled, each current sink is turned on at the Overtemperature Protection same time and allows parallel connection of current sinks Low Shutdown Current (< 15A) through Enable Pin for > 120mA per string.
