Automotive input range (10V - 50V) SEPIC LED driver
PMP6877: This reference design uses the TPS40211 current mode controller in a SEPIC converter to regulate the current in a series string of 12 to 14 LEDs (44V) at 0.5A. Efficiency is greater than 88%.
LED backlight driver 48V@0.26A
PMP6701: This SEPIC converter provides a regulated 0.26A of the current into a string of 6 to 13 LEDs. It can operate over the range of 6V to 18V and can handle a transient of 80V. The LEDs can be PWM dimmed over a 5% - 95% duty cycle and achieves an efficiency of 90%.
