The XC9213 series is an N-ch & N-ch drive, synchronous, step-down DC/DC controller IC with a built-in bootstrap driver circuit. Output will be stable no matter which load capacitors, including low ESR capacitors, are used.
The XC9213 Series is a N‑channel synchronous step‑down DC/DC controller IC with a built‑in bootstrap driver. It supports an input voltage range of 4.0 V to 25.0 V and provides a selectable output from 1.5 V to 15.0 V, with a typical oscillation frequency of 300 kHz and up to 5 A output current. The device includes current‑limit protection, soft‑start, and a voltage detector, and its standby current is as low as 4.0 µA.
Typical applications include PDAs, mobile phones, notebook computers, portable audio systems and various multi‑function power supplies. The datasheet provides pin configurations, electrical characteristics, typical performance curves, and packaging information for the TSSOP‑16 package.
