概述

Description

ISL9113ER7Z-T is a compact, high-efficiency DC-DC converter (synchronous buck-boost) from Intersil (Renesas). It’s designed for battery-powered portable electronics, regulating a battery voltage to a stable system rail across a wide input range—even as the battery voltage varies or during transient loads. Key points:
- Integrated synchronous switches and control circuitry for high efficiency.
- Buck-boost operation to maintain a fixed output over varying input.
- Protective features: overcurrent/short-circuit, undervoltage/overvoltage, thermal shutdown.
- Programmable/adjustable output with soft-start and typical light-load efficiency optimizations.
- Small packaging (ER7Z-T) suitable for compact, tape-and-reel production.
Common applications include mobile devices, cameras, wearables, and other space-constrained power-management needs where a single regulator must handle battery swings efficiently and safely.

Features

ISL9113ER7Z-T features (highlights):
- Dual high-efficiency synchronous buck DC-DC regulators
- Wide input voltage range: typically 2.5V to 5.5V
- Independent, adjustable outputs via external resistor dividers (0.8V to up to several volts per channel)
- High switching frequency (MHz range) for small external components
- Enable/shutdown control and soft-start to limit inrush
- Protection: overcurrent/short-circuit protection, thermal shutdown, UVLO
- Quiescent current optimization for battery-powered applications
- Internal current limit and robust startup behavior
- Compact packaging suitable for portable/devices (8- to 16-pin options)
Note: Exact output voltage ranges, current capability, and packaging variants should be confirmed against the latest datasheet for ISL9113ER7Z-T.

Package

It comes in an 8-pin DFN package (3×3 mm), with Tape & Reel delivery indicated by the -T suffix.

Pinout

- Pin count: 7 pins (SOT-23-7/SC70-7 package, ISL9113ER7Z-T).
- Function: A high-efficiency DC-DC converter (synchronous buck regulator) used to step down and regulate input voltage to a fixed/output voltage, with an enable/shutdown control.

Manufacturer

- Manufacturer: Intersil (now a brand of Renesas Electronics).
- What kind of company: A semiconductor company specializing in analog, mixed-signal, and power-management ICs.

Application
