Overview
The ISL9307IRTAAJYZ-T7A is an integrated mini Power Management IC (mini-PMIC) designed for low-voltage microprocessor applications. It features a dual synchronous buck converter topology with two adjustable outputs, each capable of delivering up to 1500mA. The device also integrates two low-input linear regulators (LDOs). Operating at a switching frequency of 3MHz, it supports input voltages ranging from 1.5V to 5.5V. The component is housed in a 16-TQFN package and is currently obsolete.
Feature Summary
- Integrates dual high-efficiency synchronous step-down converters
- Includes dual low-input linear regulators for noise-sensitive loads
- Optimized for single-cell lithium-ion or lithium-polymer battery systems
Applications
- Low-voltage microprocessor power supply
- Single-cell lithium-ion battery powered devices
- Lithium-polymer battery powered portable electronics
Procurement Notes
This specific part number is officially classified as obsolete and no longer manufactured by Renesas Electronics Corporation. Procurement must rely on verified parametric equivalents such as the ISL9307IRTAAJBZ-T7A. Buyers should confirm package compatibility and electrical specifications against current datasheets before acquisition.
Selection Notes
Select this component for designs requiring a compact multi-rail solution driven by a single cell battery. The 3MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the required output currents remain within the 1500mA limit for the buck channels and check LDO dropout requirements.
Part Context
The ISL9307 series represents Renesas's approach to miniaturized power management for mobile and embedded systems. This variant specifically targets applications needing both switched-mode efficiency for main rails and clean LDO regulation for sensitive analog or digital cores within a minimal footprint.
Replacement Considerations
The ISL9307IRTAAJBZ-T7A is listed as a parametric equivalent substitute. Verify pinout and thermal pad configurations match the original design layout before substitution.
