The LTC3850EUF#TRPBF from Analog Devices 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. The controller minimizes power loss and supply noise by operating the two output stages out of phase.
This device supports a wide input supply range of 4V to 24V, making it suitable for various battery chemistries and intermediate bus voltages. It offers a precision 0.8V reference and a power good output indicator. The LTC3850EUF#TRPBF is available in a 28-pin QFN package and is designed for applications such as notebook computers, portable instruments, and battery-operated digital devices.
Key features include high efficiency up to 95%, ±1% output voltage accuracy, and adjustable soft-start current ramping. It also incorporates foldback output current limiting for protection during short-circuit conditions. The MODE/PLLIN pin allows selection between Burst Mode operation, pulse-skipping mode, or continuous inductor current mode, and enables synchronization to an external clock.
The input voltage range is 4V to 24V, with an absolute maximum of 28V (for the LTC3850I variant, up to 30V).
The output voltage is adjustable from 0.8V to 6V.
The switching frequency is phase-lockable from 250kHz to 780kHz.
Efficiency is up to 95%.
The controller can deliver up to 25A output current.
It is available in a 28-lead QFN package.
The operating temperature range is -40°C to +85°C.
