Linear Technology/Analog Devices LT86xx 42V Synchronous Step-Down Regulators have high step-down ratios and small solution size. Requiring very low quiescent current with all channels on, Burst Mode� operation extends battery life to the LT86xx regulators. The LT86xx series is 42V input capable, and have high efficiency. The regulators have a separate input for each channel for added design flexibility.
