Its architecture enables Lamp Driver Modules (LDMs) to support two functions (e.g., high beam and low beam) with a single IC, reducing PCB space.<\/p>\n<\/section>\n<section>\n<p>Article content<\/p>\n<\/section>\n<section>\n<p>Article content<\/p>\n<\/section>\n<section>\n<p>Article content<\/p>\n<p>As automotive lighting transitions from traditional 12V to 48V systems, designs using the IS32LT3962 benefit from improved power efficiency, reduced thermal stress, and lower wiring harness cost and weight. The device supports a wide 5\u201380V input\/output range for 24\u201348V battery systems and enables flexible designs using buck, buck-boost, SEPIC, or boost topologies on each channel. It supports both analog and internal\/external PWM dimming per channel, with optimized soft-start for improved low duty-cycle performance. Dual analog dimming pins enable LED binning and thermal current roll-off using an external NTC, while programmable undervoltage current reduction improves robustness during supply transients. Spread spectrum operation combined with 180\u00b0 phase shifting helps reduce system-level EMI.<\/p>\n<\/section>\n<section>\n<p>Article content<\/p>\n<div aria-labelledby=\"FinancialPostTopStories6281415895898550856893465993674752\" data-account-id=\"b9d3df2fccd108b5eff3c44f573b2cd6\" data-aqa=\"widget-newsletter\" data-newsletter=\"single\" data-newsletter-component data-target-list=\"FP_HeadlineNews\" data-widget=\"newsletter\">\n<p>By signing up you consent to receive the above newsletter from Postmedia Network Inc.<\/p>\n<\/div>\n<\/section>\n<section>\n<p>Article content<\/p>\n<p><strong>Single IC, Multiple Lighting Functions<\/strong><br \/>The dual output channel IS32LT3962 enables independent channel brightness control, with combined analog and internal\/external PWM dimming; designers can enable compact lighting solutions. \u201cWith the IS32LT3962, automotive lighting designers can feature multiple applications such as headlamp high\/low beam, turn signal, DRL using just one IC; this also reduces the wiring complexity for the system\u201d, said Aaron Reynoso, Dir. of Analog Marketing. \u201cThis multi-topology, dual-channel architecture delivers precise, independent LED string controls with flexible multi-mode dimming.
