ISL98607BEIAZ-T

Special Purpose Regulators Overview

The ISL98607BEIAZ-T is a high-efficiency power supply IC designed for small size displays, such as those in smartphones. It integrates a boost regulator, LDO, and inverting charge pump to generate dual output rails of +5V and -5V by default, adjustable up to ±5.7V via I2C. The device operates within an input voltage range of 2.8V to 4.4V and achieves over 85.5% efficiency with a 12mA load between outputs. It features fully integrated synchronous rectification FETs and compensation circuits, minimizing BOM count and reducing solution PCB area to 21mm². The unit is housed in a 20-lead TQFN package.

Special Purpose Regulators Procurement Notes

Verify the specific suffix BEIAZ against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with I2C bus requirements and check for any recent product change notifications regarding manufacturing sites or materials. Confirm availability status directly with authorized distributors as stock levels fluctuate.

Special Purpose Regulators Selection Notes

Select this component when designing for small form factor displays requiring dual voltage rails from a single cell lithium-ion source. It is suitable for applications prioritizing high efficiency and minimal PCB footprint. Consider the 2.8V to 4.4V input range and the need for I2C programmability when evaluating system architecture constraints.

Special Purpose Regulators Part Context

The ISL98607 belongs to the Renesas (formerly Intersil) specialized PMIC family focused on display power management. It addresses the trend toward smaller mobile devices by integrating multiple power stages into a single compact package. This series supports the industry shift towards highly efficient, space-constrained power designs for portable electronics.

Special Purpose Regulators Replacement Considerations

Check for direct pin-to-pin replacements within the ISL98607 series or compatible Renesas display PMICs. Verify that alternative components support the same ±5V default outputs and I2C adjustability. Ensure thermal performance and package dimensions match the existing design constraints.
