The controller drives an external N-channel MOSFET. ## 200 kHz switching — inductor sizing trade-off Switching frequency is fixed at 200 kHz. No clock-sync option here. ## Wide input range, single output, no synchronous rectifier Supply range runs from 3.5 V to 36 V. The single output can be configured for positive or negative voltage. There is no synchronous rectifier. ## Active lifecycle and ROHS3 compliance Linear Technology (now Analog Devices) lists the LTC1624CS8#PBF as Active with ROHS3 compliance. No last-time-buy risk for new designs. The 8-SOIC package is widely stocked and easy to source through independent distribution. ## 8-SOIC — rework-friendly footprint The 8-SOIC (0.154-inch body width, 3.90 mm) is a standard gull-wing package. Under a hot-air station the part lifts cleanly with minimal pad disturbance — no hidden thermal pad underneath. Reflow profile follows standard lead-free (ROHS3) solder paste. The tube shipping medium is fine for bench work; if you need tape-and-reel for pick-and-place, order the LTC1624CS8#TRPBF variant instead.","metaTitle":"LTC1624CS8#PBF DC/DC Controller, Buck/Boost/SEPIC, 200 kHz","metaDescription":"LTC1624CS8#PBF is an active DC/DC controller from Analog Devices supporting buck, boost, and SEPIC topologies.

The controller supports SEPIC topology directly — just add the coupling capacitor and second inductor. The wide input range (3.5 V to 36 V) and single N-channel MOSFET drive make it a good fit for SEPIC designs that generate a regulated output from a varying input like a battery."},{"question":"What is the switching frequency of the LTC1624CS8#PBF?","answer":"The switching frequency is fixed at 200 kHz.

It operates at 150 kHz, adds soft-start, and includes synchronous rectification for higher efficiency. Note the LTC1625CS#TRPBF is tape-and-reel, not tube. For a simpler buck-only controller, the LTC1148CS#PBF runs at 250 kHz with synchronous rectification but does not support boost or SEPIC."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC1624CS8PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC1624CS8PBF when reusing this data.
