Analog Devices Inc. LTC3895EFE is a high-voltage, synchronous buck (step-down) DC-DC controller. This component features a wide input voltage range of 4V to 140V and supports a maximum duty cycle of 100%. The switching frequency is adjustable from 50kHz up to 900kHz, with current limit, enable, frequency control, phase control, power good, and soft start control features. It is designed for single output positive configurations and utilizes transistor driver output. The LTC3895EFE is packaged in a 38-TSSOP-EP (38-TFSOP) with exposed pad, suitable for surface mounting. This controller is commonly employed in power supply designs for industrial, automotive, and telecommunications applications requiring efficient voltage regulation from high input voltages.
