Analog Devices ADP1829 Datasheet
The ADP1829 is a versatile dual‑channel, interleaved synchronous buck controller that generates two independent output rails from an input of 3.0 V to 20 V (wide power‑stage range 1 V‑24 V). It offers fixed‑frequency operation at 300 kHz or 600 kHz and can be synchronized up to 1 MHz. Integrated features include a linear regulator, soft‑start, thermal overload, current‑limit and reverse‑current protection, as well as independent Power‑OK outputs and voltage‑tracking for sequencing or DDR termination.
Typical applications listed are telecommunications and networking systems, medical imaging, base‑station power, set‑top boxes, printers and DDR termination. The device is supplied in a 5 mm × 5 mm, 32‑lead LFCSP package and is rated for operation from –40 °C to +125 °C.
