It operates from a 4.5V to 42V supply rail, switching between 100kHz and 750kHz with clock sync support for noise-sensitive systems. The 20-TSSOP package with exposed pad helps pull heat into the PCB ground plane, and the junction temperature range of -40°C to 125°C suits automotive and industrial environments where the ambient hits the high side. ## Wide 4.5V–42V supply — what it means for the BOM The 4.5V to 42V Vcc/Vdd range is the headline number for fit. It covers 12V and 24V industrial buses, automotive battery rails during cold-crank and load-dump transients, and battery-powered systems that sag below 5V. The 100% duty cycle capability lets the controller pass the input straight through in dropout, useful when the input dips close to the output target. No synchronous rectifier on-chip — you add external MOSFETs and catch diodes; the controller drives them with a PWM signal. ## Active production — no LTB risk Marked as current/active in the lifecycle record. No last-time-buy notice on file, no NRND flag. ## 20-TSSOP-EP — thermal and layout notes The exposed pad on the 20-TSSOP is the primary thermal path. The PCB layout should stitch vias under the pad to the ground plane — without that, junction temperature climbs fast above 400mA continuous external load. The Tube delivery means parts arrive loose in a plastic tube; no tape-and-reel, so pick-and-place requires a tube feeder or manual handling.","metaTitle":"LT8711IFE#PBF Synchronous Controller, Buck/Boost/SEPIC","metaDescription":"LT8711IFE#PBF is an active-production PWM controller IC from Analog Devices.
