EL7512CYZ-T7

DC DC Switching Controllers Overview

The EL7512CYZ-T7 is a boost DC-DC switching controller IC manufactured by Renesas Electronics Corporation. It operates within a switching frequency range of 530kHz to 1.2MHz and supports a maximum duty cycle of 90%. The device features a single positive output configuration with a transistor driver stage, powered by a supply voltage (Vcc/Vdd) between 2V and 12V. It is housed in a 10-MSOP surface-mount package and is rated for an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Integrated soft-start functionality to manage inrush current during startup
• Supports frequency control for flexible switching speed adjustment
• Includes low battery detection capability for power management

DC DC Switching Controllers Applications

• Battery-powered portable electronic devices requiring voltage step-up
• Systems utilizing single-cell lithium-ion or alkaline batteries
• General-purpose boost converter circuits in consumer electronics

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'T7' indicates tape-and-reel packaging if required for automated assembly, as standard versions may use tubes. Confirm RoHS3 compliance status for environmental regulations. Check for End-of-Life (EOL) notifications from Renesas, as availability may be limited. Ensure design-in compatibility with existing PCB footprints for the 10-MSOP package.

DC DC Switching Controllers Selection Notes

Select this component when a non-synchronous boost topology is sufficient for the application's efficiency requirements. Consider the 2V to 12V input range suitability for single-cell battery sources. Evaluate the 530kHz to 1.2MHz frequency range against external inductor size constraints. Verify that the 10-MSOP package dimensions fit the mechanical enclosure limits.

DC DC Switching Controllers Part Context

This part belongs to the EL7512 series of boost controllers from Renesas (formerly Intersil). It is designed for applications needing efficient voltage elevation from low-voltage sources. The series typically offers compact solutions for portable equipment, distinguishing itself through integrated control features like soft-start and frequency synchronization options within a small footprint.

DC DC Switching Controllers Replacement Considerations

Consult Renesas documentation for direct pin-compatible alternatives within the EL75xx series. Verify electrical parameters such as switching frequency and input voltage range match the original design requirements before substitution.
