LTC3850EUF#TRPBF. Description

Short technical summary and product information.

The LTC3850EUF#TRPBF from LT is a high-performance dual synchronous step-down switching regulator controller. It drives all N-channel power MOSFET stages and operates with a constant-frequency current mode architecture, allowing for a phase-lockable frequency up to 780kHz. Power loss and supply noise are minimized by operating the two controller output stages out of phase.

 

This controller supports a wide input supply range of 4V to 24V, with an output voltage adjustable from 0.8V to 6V. It offers high efficiency up to 95% and features a precision 0.8V reference. The device includes independent TK/SS pins for controlled output voltage ramp-up during startup and current foldback for MOSFET heat dissipation during short-circuit conditions.

 

The LTC3850EUF#TRPBF is available in a low-profile 28-pin 4mm x 4mm QFN package, suitable for surface mount (SMD/SMT) applications. Its design is optimized for applications such as notebook computers, portable instruments, and battery-operated digital devices.
