Targeted at backlight applications, the PWM dimming allows brightness control without shifting the LED colour temperature — the duty cycle adjusts the average current while the peak current stays at the set 25 mA. ## Package and board-fit for rework Housed in an 8-HVSON (3x3 mm) package with an exposed thermal pad, the part sits flat on the board and the pad needs a good solder joint to the ground plane to pull heat out. The 8-VFDFN footprint is standard — the pad layout and stencil aperture for the thermal slug matter more for reliability than the signal pins themselves. Will it survive the hot air? Yes — the exposed pad gives you a thermal path to the board, so a rework station with bottom preheat lifts the part cleanly without lifting the pads.","metaTitle":"NXP PCA9633TK,118 LED Driver, 4-ch PWM, 25mA, 8-HVSON","metaDescription":"NXP PCA9633TK,118 4-channel LED driver with PWM dimming, 25 mA per channel, 2.3-5.5 V supply.
