The Analog Devices Inc. LTC3890HUH-TRPBF is a high-performance, dual-output PolyPhase® synchronous buck controller. This 32-QFN (5x5) packaged device offers a wide input voltage range from 4V to 60V, enabling versatile power supply designs. It features independent output control for two phases, facilitating efficient step-down DC-DC conversion. The LTC3890HUH-TRPBF supports selectable switching frequencies between 105kHz and 835kHz, with a typical operating range of 350kHz to 535kHz, allowing optimization for efficiency and component size. Control features include current limit, enable, frequency control, phase control, power good, soft start, and tracking. The maximum duty cycle is 99%, and it incorporates synchronous rectification for enhanced efficiency. This controller is suitable for applications in telecommunications, data centers, and industrial power systems.
