It drives up to six LED strings, each regulated at 30 mA, with a maximum output voltage of 44 V. The switching frequency is programmable from 200 kHz to 2.5 MHz, letting you trade off inductor size against efficiency. ## Wide input and temperature range Dimming is supported via both analog and PWM methods, giving flexibility for color mixing or brightness control in display backlighting and architectural lighting. Housed in a 24-lead WFQFN with exposed pad (4 mm × 4 mm), the part is surface-mount and hand-solderable with a hot-air station — the exposed pad helps thermal management. The supplier device package is 24-QFN (4x4). Supplied in tube packaging, suitable for prototype runs and small-batch production. The ROHS3 compliance means no lead, mercury, or cadmium restrictions for EU markets.","metaTitle":"LT3598IUF#PBF Analog Devices LED Driver, 6-Ch Boost, 44V","metaDescription":"LT3598IUF#PBF DC DC regulator, step-up boost, 6 outputs at 30mA each, 44V output.
