The LTC3850EUF#TRPBF from Analog Devices is a high-performance dual synchronous step-down switching regulator controller. It features a constant-frequency current mode architecture, allowing for a phase-lockable frequency range of 250kHz to 780kHz. This design minimizes power loss and supply noise by operating the two controller output stages out of phase.
This controller supports a wide input supply range of 4V to 24V, making it suitable for various battery chemistries and intermediate bus voltages. It includes features like OPTI-LOOP® compensation for optimized transient response, a precision 0.8V reference, and a power good output indicator. The device also offers adjustable soft-start for controlled output voltage ramping and foldback current limiting for protection during short-circuit conditions.
The LTC3850EUF#TRPBF is available in a 28-pin 4mm x 4mm QFN package, designed for surface mounting. Its dual N-channel MOSFET synchronous drive and 2-phase operation contribute to high efficiency, up to 95%.
Applications for this controller include notebook and palmtop computers, portable instruments, battery-operated digital devices, and DC power distribution systems.
