Overview
The ET8215 is a low-power synchronous boost switching regulator IC from ETEK Microelectronics. It features a fixed output voltage of 5V and supports an output current of up to 1A. The device operates at a switching frequency of 2.5 MHz, integrating power switches and employing synchronous rectification technology for high efficiency. It maintains stable output regulation even when the system battery voltage drops to its minimum level.
Feature Summary
- Integrates power switches with synchronous rectification technology
- Maintains output voltage stability at minimum battery voltage conditions
- Designed for low-power operation in portable applications
Applications
- Portable communication equipment
- Battery-powered devices requiring stable 5V supply
- Systems operating at minimum battery voltage levels
Procurement Notes
Verify the exact part marking and package type against official ETEK Microelectronics documentation before procurement. Ensure compatibility with your system's input voltage range and load requirements. Confirm that the supplier provides genuine components with traceable origins to avoid counterfeit risks. Check for any specific ordering suffixes that may indicate package variations or temperature grades.
Selection Notes
Select the ET8215 when a compact, efficient 5V boost solution is needed for battery-operated systems. Its 2.5 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 1A output capability and synchronous rectification benefits for improved efficiency under varying load conditions. Ensure the application environment supports the thermal performance characteristics defined in the datasheet.
Part Context
ETEK Microelectronics specializes in high-performance analog integrated circuits and power management solutions. The ET8215 belongs to their portfolio of switching regulators designed for mobile and portable electronics. This component addresses the need for reliable voltage boosting in space-constrained, battery-powered devices where efficiency and size are critical design parameters.
Replacement Considerations
Consult official ETEK Microelectronics documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other manufacturers' boost converters without verifying pinout, electrical specifications, and thermal characteristics. Verify that any replacement maintains the required 5V output and 1A current capability.
