ADI Synchronous Buck Regulator LT8609AJDDM-3.3-PBF
LT8609AJDDM-3.3-PBF
LT8609AJDDM-3.3-PBF is a high-efficiency synchronous step-down DC-DC converter from Analog Devices Inc. (ADI). Offered in a DFN-10 package, it operates over a 3 V to 42 V input range and delivers up to 3 A of output current. The switching frequency is programmable from 200 kHz to 2.2 MHz, allowing optimization of efficiency and EMI. Integrating power switches and synchronous rectification, the device achieves a peak efficiency of 94 % and draws only 2.5 µA in no-load standby while maintaining regulation. Designed for harsh automotive (infotainment, ADAS) and industrial-automation environments, it tolerates voltage transients—including cold-crank events—while enabling a compact, reliable power solution.
ADI’s DC-DC portfolio spans milliwatts to kilowatts and is split into three camps—µModule fully-integrated packages, high-power controllers, and low-noise monolithics—leveraging proprietary Silent Switcher, isoPower and multiphase current-sharing technologies to deliver >97 % efficiency, 300 W/in³ power density, 10 µVRMS output noise and CISPR 25 Class 5 EMI. Operating from 2.75 V–150 V input and delivering 0.8 V–96 V output, the parts offer PMBus-based digital trimming and telemetry, providing one-stop power solutions for automotive 48 V/800 V systems, 5G RF rails with 200 A transients, medical CT high-voltage supplies and low-power TWS earbuds alike.As a distributor, Mandu Technology offers customers a wide variety of storage-product solutions.
