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 features a constant-frequency current mode architecture.
This controller supports a phase-lockable frequency range of 250kHz to 780kHz, minimizing power loss and supply noise by operating the two output stages out of phase. It boasts a wide input supply range of 4V to 24V and achieves high efficiency of up to 95%. The device includes a precision 0.8V reference with ±1% output voltage accuracy and a power good output indicator.
Designed for flexibility, the LTC3850EUF#TRPBF supports independent TK/SS pins for controlled output voltage ramp-up, and current foldback limits MOSFET heat dissipation during short-circuit conditions. The MODE/PLLIN pin allows selection between Burst Mode, pulse-skipping, or continuous inductor current modes, and enables synchronization to an external clock.
Available in a 28-pin QFN package, this controller is suitable for applications such as notebook computers, portable instruments, and battery-operated digital devices.
