SY89832UMG-TR

SY89832UMG-TR is a power-management IC from Silergy (SY) in a compact UMG package with Tape-and-Release (TR). It is a high‑efficiency switching regulator intended for DC‑DC conversion in portable and compact power supplies.
Key points:
- Synchronous switching regulator with integrated MOSFETs (typical buck topology)
- Adjustable output via external resistor network
- Wide input range suitable for battery/USB-style inputs
- High efficiency, soft-start, and an enable pin
- Protections: over‑current/short‑circuit, over‑temperature, and undervoltage lockout
- Very small footprint in UMG-TR package; designed for automatic assembly
Typical applications:
- Low-voltage rails for mobile devices, USB power modules, and consumer electronics
- Power adapters and battery-powered systems requiring compact, efficient DC‑DC conversion
Note:
- For exact electrical specs, pinout, and reference designs, consult the official datasheet and application notes.

- Pin count: 32 pins (QFN, UMG package)
