The LTC3850EUF#TRPBF is a high-performance dual synchronous step-down switching regulator controller manufactured by LT. It features a constant-frequency current mode architecture, allowing for a phase-lockable frequency up to 780kHz. The controller drives all N-channel power MOSFET stages, minimizing 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 and provides an output voltage range of 0.8V to 6V with an accuracy of ±1% for the 0.8V reference. It achieves high efficiency, up to 95%, and offers features like OPTI-LOOP® compensation for optimized transient response, independent TK/SS pins for controlled output voltage ramp-up, and foldback current limiting for 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 well-suited for applications such as notebook computers, portable instruments, and battery-operated digital devices requiring efficient power conversion.
Input voltage range is 4V to 24V. Output voltage is adjustable from 0.8V to 6V.
The device is housed in a QFN-28 package.
Operating temperature range is -40°C to +85°C.
Switching frequency is phase-lockable from 250kHz to 780kHz.
Maximum output current is 25A.
Efficiency is up to 95%.
Quiescent current is typically 30µA.
