Analog Devices Inc. LTC3829EFE PolyPhase® Buck Regulator. This is a high-performance three-phase, synchronous buck controller designed for step-down DC-DC conversion. Operating from a 4.5V to 38V supply, it features a wide switching frequency range of 250kHz to 770kHz, allowing for optimization of efficiency and component size. The device supports a maximum duty cycle of 94% and provides precise control over output voltage and current. Key control features include current limit, enable, frequency control, power good indication, soft start, and tracking. The LTC3829EFE is delivered in a 38-TSSOP-EP package for surface mounting. Its robust design makes it suitable for demanding applications in automotive, industrial, and telecommunications sectors.
