ISL98607EIAZ-TR5640

Special Purpose Regulators Overview

The ISL98607EIAZ-TR5640 is a high-efficiency power supply 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. The input voltage range spans from 2.8V to 4.4V, supporting single-cell Li-ion battery applications. Output voltages are adjustable up to ±5.7V with 50mV steps via an I²C interface. The device features fully integrated synchronous rectification FETs and achieves over 85.5% efficiency with a 12mA load between outputs.

Special Purpose Regulators Procurement Notes

Verify the specific suffix TR5640 against official Renesas documentation to confirm tape and reel specifications or lot traceability details. Ensure the component matches the standard ISL98607 electrical characteristics and package options. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before procurement.

Special Purpose Regulators Selection Notes

Select this component when designing power systems for small displays requiring dual polarity rails from a single lithium-ion source. It is suitable for space-constrained designs due to its minimal solution PCB area. Consider the I²C adjustability if precise voltage tuning is required. Verify that the operating temperature range meets the environmental conditions of the target application.

Special Purpose Regulators Part Context

The ISL98607 belongs to Renesas' specialized PMIC family focused on display power management. It replaces discrete solutions by integrating multiple regulators into a single chip. The series offers various package options including WLCSP and TQFN to accommodate different form factors. This integration reduces component count and simplifies layout for mobile and portable electronics.

Special Purpose Regulators Replacement Considerations

Check for direct pin-to-pin replacements within the ISL98607 series with different suffixes. Verify compatibility with existing board layouts if substituting with other display power ICs. Ensure alternative components support the same input voltage range and output configurations.
