The LTC3853IUJ#PBF is a triple output buck DC-DC controller manufactured by Analog Devices Inc. This integrated circuit is designed for efficient power conversion, supporting positive step-down outputs. It operates within an input voltage range of 4.5V to 24V and offers a high switching frequency adjustable between 250kHz and 750kHz, enabling compact power supply designs.
The controller features three synchronous outputs and includes essential control functions such as current limit, enable, frequency control, power good indication, soft start, and tracking. It is housed in a 40-pin QFN package with an exposed pad, suitable for surface mounting on PCBs. The operating temperature range is -40°C to 125°C (TJ).
This device is well-suited for applications requiring multiple regulation channels, including industrial systems, telecom equipment, networking devices, and server motherboards. Its design incorporates advanced monitoring and protection features for reliable operation under demanding conditions.
