Description
LTC3618EUF#TRPBF is Linear Technology’s (now Analog Devices) part number for the LTC3618 dual switching regulator in the EUF package, suppliedPb-free in tape-and-reel. The device packages two high-efficiency switching regulators on one chip, intended for compact, portable-power designs.
Key idea: two regulator channels on a single IC that use switching regulators (with external inductors and feedback networks) to generate two rails from a common input. It typically supports features useful for mobile or dense power supplies, such as enable control, soft-start, and protection functions (overcurrent/thermal, undervoltage, etc.). The two channels can be used to generate independent rails or run in configurations that improve ripple and transient performance.
Why it’s used: to create core or other supply rails for FPGAs/GPUs, ASICs, memory, or other low-voltage loads in compact devices.
For exact specs (input range, output voltages, current capability, switching frequency, pinout), consult the LTC3618 datasheet and product page.

Equivalent
Direct drop-in equivalents for LTC3618EUF#TRPBF do not exist. For a replacement, use Analog Devices’ cross-reference tools or distributor searches to find a similar multi-output buck regulator with equivalent input range and current rating. If exact pinout is required, you may need a different package variant from the same family or redesign to a non‑drop-in substitute.
