PMP20305 is an LED driver circuit reference design using the LM5022-Q1 boost controller IC and two types of constant-current methods to drive 4 strings of LEDs. Two of the LED strings utilize the TL431 voltage reference as a driver to perform a constant current source, while the other two strings utilize the TL4242 linear LED driver IC, which also features a PWM-controlled brightness adjust scheme. The input voltage range of the circuit is 6Vin to 16Vin (24Vin Peak). The output of the LM5022-Q1 boost converter is set to 26.9Vout and is capable of supplying a total of 0.4A of current to the loads.
