The XCM517 series is a multi combination module IC which comprises of two 600mA driver transistor built-in synchronous step–down DC/DC converter. The XCM517 series is available in an ultra small package USP-12B01 suited for space conscious applications.
The XCM517 series from Torex is a compact dual‑output synchronous step‑down DC/DC converter offered in an ultra‑small USP‑12B01 package. It integrates a P‑channel driver and an N‑channel switching transistor, allowing operation with only a coil and two external ceramic capacitors. The device supports input voltages from 2.7 V to 6.0 V and provides up to 600 mA output current per channel.
The series includes variants with PWM control (XCM517xA/B) and automatic PWM/PFM control (XCM517xC/D). Key features are high efficiency (up to 92 % typical), soft‑start, built‑in UVLO, and low standby current. Detailed pin assignments, block diagrams, and electrical characteristics are provided for design integration.
