ISL91110IINZ-T

ISL91110IINZ-T is a compact, high‑efficiency DC‑DC regulator from Intersil (Renesas). It belongs to the ISL9110x family and is intended for battery‑powered portable electronics. The device typically integrates switching MOSFETs and control logic to regulate an input source (such as a battery or adapter) to a stable output, with either fixed or adjustable Vout via feedback resistors. Features commonly include soft‑start, an enable/shutdown input, and protection circuits (UVLO/OVLO, overcurrent/short‑circuit, thermal shutdown). It supports fast transient response and high efficiency over a wide load range. The INZ suffix denotes the package/variant; T indicates tape‑and‑reel packaging in a compact surface‑mount form factor. Typical applications: smartphones, wearables, IoT sensors, and other portable devices. For exact electrical specs (Vin range, Vout range, max current, switching frequency), refer to the official Renesas datasheet for ISL91110IINZ‑T.

- Pin count: 8 pins
