The LTC3807EUDC#PBF is a high-performance step-down DC/DC controller designed for driving an all N-channel synchronous power MOSFET stage. It operates within a wide input voltage range of 4V to 38V, with a maximum input voltage of 40V. The output voltage can be programmed between 0.8V and 24V, making it suitable for various applications including automotive systems and battery-powered devices. This controller features a low quiescent current of 50OºA, which is beneficial for extending battery life in portable applications. It supports phase-lockable frequency operation from 75kHz to 750kHz and allows for programmable fixed frequency settings between 50kHz and 900kHz. The LTC3807 also includes selectable modes for continuous, pulse-skipping, or low ripple burst mode operation at light loads, along with adjustable output voltage soft-start and tracking capabilities. Additional features include output overvoltage protection, a power good output voltage monitor, and selectable current limit settings. The device is available in a compact 20-pin QFN package, making it suitable for space-constrained designs. The LTC3807EUDC#PBF is rated for operation over a temperature range of -40¬8C to 125¬8C, ensuring reliability in demanding environments.
