Silent Switcher®2 step-down for automotive power rails
The Analog Devices LT8646SIV#WPBF is a Silent Switcher®2 synchronous buck regulator delivering 8 A continuous output from a 3.4 V to 65 V input range. It integrates the high-side and low-side switches with internal compensation, reducing external component count to an inductor, a few capacitors, and feedback resistors. The adjustable output is set from 0.97 V up to 12 V. AEC-Q100 qualification and a junction temperature range of -40°C to 125°C make it a direct fit for automotive ECU, ADAS, and infotainment power supplies where board space is tight and thermal performance under hood matters.
8 A output and thermal management in the 32-LQFN package
Rated for 8 A continuous output, the LT8646SIV#WPBF uses a 32-lead LQFN (6 mm x 4 mm) with an exposed pad. The synchronous rectifier reduces dropout and improves efficiency at high step-down ratios.
Lifecycle and compliance
The LT8646SIV#WPBF carries an Active lifecycle status with ROHS3 compliance. AEC-Q100 qualification is confirmed, supporting PPAP submissions for automotive programs.
