CAT4106YP-T2

CAT4106YP-T2 is a 6W quad channel DC/DC LED driver with diagnostics in a 16 pin TSSOP package. It is an integrated multi-channel LED driver and high power DC/DC converter suitable for powering backlighting applications up to a total of 6 watts. Up to four matched LED strings can be accurately programmed with uniform drive current set by a single external resistor. Each output channel is suitable for LED string voltages of up to 36V. The driver automatically adjusts the output voltage to drive the highest forward voltage string with the minimum headroom voltage maximizing the efficiency. High resolution dimming control is achieved by the EN/PWM logic pin which supports multiple frequencies. This ensures precise PWM dimming control while the device remains fully biased. In addition, when held at logic low, the device to enter a full shutdown zero current mode. External programming resistors set the minimum and maximum voltage limits for the acceptable window of operation for LED strings.
