ISL91110IINZ-T

ISL91110IINZ-T is a high-efficiency, integrated switching regulator (DC-DC converter) from Renesas Intersil. It’s designed for portable, battery-powered electronics and provides a regulated output from a wide input range using internal MOSFETs and PWM control.
Key points:
- Function: switching regulator (buck/buck-boost family variants exist) capable of delivering a stable rail for microprocessors and peripherals.
- Features: adjustable output via external feedback resistors, soft-start, enable control, and modes for better light-load efficiency.
- Protections: undervoltage lockout, overcurrent/short-circuit protection, thermal protection.
- Packaging/variants: “IINZ-T” specifies the tape-and-reel package and option family; exact pinout, input/output ranges, and performance depend on the specific variant—refer to the datasheet for exact figures.
- Applications: smartphones, wearables, IoT sensors, and other compact power-management needs.
Note: For precise electrical specs (input range, output voltage, efficiency, frequency, pinout), consult the official ISL91110IINZ-T datasheet.
