It accepts a 4.5V to 38V input rail and delivers two independent regulated outputs — one adjustable from 0.6V to 3.5V, the other from 0.6V to 5V — controlled via a 6-bit VID code for dynamic voltage scaling. The -40°C to 125°C operating temperature range qualifies it for outdoor and under-hood environments without derating. ## Package and mounting Housed in a 44-lead WFQFN with exposed pad (7x7 mm body), the LTC3877EUK#PBF is a surface-mount part requiring a thermal via array under the pad for effective heat transfer to the PCB ground plane. The exposed pad is the primary thermal path — without adequate via stitching, junction temperature rises quickly above 400 mA continuous load per output. ## Lifecycle and sourcing reality ROHS3 compliant. No official second source or pin-compatible replacement is recorded; for dual-sourcing resilience, evaluate the LTC3877 family's other VID-code variants or a discrete controller pair.","metaTitle":"LTC3877EUK#PBF Dual-Output VID Controller, 4.5V–38V Input","metaDescription":"LTC3877EUK#PBF from Analog Devices: dual 6-bit VID controller, 4.5V–38V input, 0.6V–5V outputs, 44-QFN, -40°C to 125°C.
