The MAX20056B is a 6-channel LED driver that integrates a DC-DC switching boost/SEPIC controller and six 120mA current sinks. A current-mode switching DC-DC controller provides the necessary voltage to the strings of HB LEDs. An internal current-mode switching DC-DC controller supports boost, SEPIC, or coupled-inductor buck-boost topologies and operates in a programmable frequency range between 400kHz and 2.2MHz. Current-mode control provides fast response and simplifies loop compensation. An adaptive output-voltage-adjustment scheme minimizes power dissipation in the LED current sinks. An external resistor sets the channel currents to the same value in the range of 20mA to 120mA. The device features logic-controlled pulse-width modulation (PWM) dimming with minimum pulse widths as low as 500ns, and either phase-shifted LED strings or standard dimming control. When phase shifting is enabled, each string is turned on at a different time, reducing the input and output ripple, as well as audible noise. With phase shifting disabled, each current sink is turned on at the same time and allows parallel connection of current sinks for > 120mA per string.
