Product details

What it is and where it fits

The TB62771FTG,8,EL is a 4-channel DC-DC regulator LED driver in a step-up (boost) topology, designed for backlight applications. Each channel delivers up to 150 mA at a maximum output voltage of 45 V, with PWM dimming control. It operates from a 4.75 V to 40 V supply rail and switches between 200 kHz and 2 MHz, letting you tune the inductor and capacitor size for the board space versus ripple trade-off. The 20-WQFN (4x4 mm) package with exposed pad sinks the heat from the internal switch into the PCB copper pour.

Active production and compliance

It is ROHS3 Compliant, so it passes the current EU material restrictions without an exemption expiry date.
