Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with standard SMD/SMT assembly processes. Confirm moisture sensitivity level (MSL) handling requirements prior to PCB placement. Validate that the 32-lead TQFN-EP package aligns with your board layout constraints and thermal design goals.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring a single-stage solution for both step-up and step-down operations on peripheral rails. Consider the 6 A current capability and 1 MHz frequency for balancing efficiency and footprint. Evaluate the 3.8 V to 24 V input range against your system's battery or adapter characteristics. Ensure the TQFN-EP-32 package fits your available real estate.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL95338 series from Renesas Electronics Corporation, specifically engineered for power management in mobile computing devices.
