LT8390EFE#TRPBF
Analog DevicesLT8390EFE#TRPBF is an Analog Devices 60 V synchronous 4-switch buck-boost controller in a 28-lead TSSOP with exposed pad, supplied on tape and reel — for rails that must stay regulated as the input crosses the output, such as 12 V automotive and industrial buses fed from 4 V to 60 V. The selection point is the single-inductor 4-switch architecture with spread-spectrum frequency modulation: it bucks, boosts and passes through seamlessly at up to 98% efficiency, and the spread spectrum plus 150 kHz to 650 kHz adjustable, synchronizable switching keeps EMI filter size down in CISPR-sensitive designs; input/output current monitoring, a power-good flag and integrated bootstrap diodes cut external parts. Selection advice: the EFE#TRPBF code is the E-grade (-40 to +125 °C junction) TSSOP on tape and reel — the EUFD QFN variant suits height-constrained layouts; for switching up to 2 MHz choose the LT8390A sibling instead. Analog Devices keeps the LT8390 in production; parameters verified against the ADI LT8390 datasheet (Rev. C).
