Operating from a 6.35 V to 14 V bias supply (Vcc/Vdd), the controller generates a regulated output through a single-phase, positive-output transistor driver. The 1-output configuration suits point-of-load rails that need a voltage higher than the input bus — common in telecom backplanes, battery-powered systems, and automotive pre-boost stages. ## Control features and clock sync On-chip control features include Enable, Power Good flag, and Soft Start. The Power Good output monitors the regulated rail and can sequence downstream converters or reset a microcontroller on power-up. Soft Start ramps the output voltage gradually, limiting inrush current from the input supply during start-up. The clock synchronization input (Clock Sync = Yes) lets the controller lock to an external clock signal, shifting the switching frequency away from sensitive bands in RF or instrumentation systems. Without an external clock, the part runs from its internal oscillator; with one, multiple converters can be phase-aligned to reduce input ripple current.","metaTitle":"LTC3813EG#PBF Boost Controller, 28-SSOP, Active","metaDescription":"Analog Devices LTC3813EG#PBF boost controller IC, 6.35V-14V supply, synchronous rectifier, -40°C to 85°C.

The package is also different — the LTC3814 uses a 28-SSOP with exposed pad (FE package) versus the standard SSOP-28 on the LTC3813. For designs that require clock sync and the wider Vcc range, the LTC3813EG#PBF is the correct fit; the LTC3814 is a lower-cost option when those features are not needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC3813EG~4PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC3813EG~4PBF when reusing this data.
