Overview
The ISL9307IRTWCNJZ-T7A is an integrated mini Power Management IC (mini-PMIC) designed for low-voltage microprocessor applications. It features a 1.5V to 5.5V input voltage range and operates within -40°C to 85°C. The device integrates two synchronous step-down converters with 1.5A output current capability and two 300mA low-dropout (LDO) regulators, providing four total outputs in a 16-WQFN package.
Feature Summary
- Integrates dual high-efficiency synchronous buck converters and dual LDO regulators
- Supports wide input voltage range suitable for single-cell lithium battery sources
- Compact surface-mount packaging optimized for space-constrained designs
Applications
- Powering low-voltage microprocessors
- Battery-operated portable electronic devices
- Multi-rail power systems for embedded applications
Procurement Notes
Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix matches the required pinout and thermal characteristics. Check for end-of-life status or last-time-buy notices as availability may be restricted. Ensure compliance with RoHS3 specifications for environmental regulations.
Selection Notes
Select this component when a compact solution is needed for powering multiple low-voltage rails from a single cell. Compare against other mini-PMICs based on total output current requirements and thermal performance. Verify that the 16-WQFN footprint fits the PCB layout constraints and that the switching frequency meets EMI requirements.
Part Context
This part belongs to the ISL9307 family of integrated power management solutions. It is specifically engineered to replace discrete regulator designs, reducing bill of materials and board space. The series targets mobile and industrial applications requiring efficient power conversion from lithium-based sources.
Replacement Considerations
Check for direct pin-compatible alternatives within the RAA211xx series if available. Verify functional equivalence regarding output currents and control interfaces before substitution.
