Overview
The S-8520E28MC-BJNT2U is a step-down switching regulator controller manufactured by ABLIC Inc. It operates with a fixed switching frequency of 300 kHz and features an ultra-low quiescent current of 100 uA. The device supports an input voltage range from 2.5 V to 16 V and provides a fixed output voltage of 2.8 V. It utilizes PWM control topology and is housed in a compact SOT-23-5 package, designed for efficient power management in portable applications.
Feature Summary
- Ultra-low quiescent current consumption for extended battery life
- Fixed 300 kHz switching frequency for compact external component sizing
- Integrated enable pin for precise power management control
Applications
- Portable electronic devices requiring low standby power
- Battery-powered consumer electronics
- General-purpose DC-DC conversion systems
Procurement Notes
Verify the specific suffix BJNT2U against official ABLIC documentation to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Cross-reference the part number with authorized distributors to confirm current availability status and lead times prior to finalizing procurement plans.
Selection Notes
Select this component when a fixed 2.8 V output is required from a 2.5 V to 16 V input source. The 300 kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load requirements do not exceed the internal switch capabilities defined in the datasheet. Consider thermal performance within the SOT-23-5 package constraints for high-current applications.
Part Context
This part belongs to the S-8520 series of step-down switching regulators from ABLIC. The series is characterized by low quiescent current operation and fixed output voltage options. The S-8520E28MC variant specifically targets applications needing a stable 2.8 V rail with minimal self-consumption, fitting into the broader PMIC portfolio for mobile and handheld devices.
Replacement Considerations
Check for direct substitutes within the S-8520 family offering different fixed voltages or frequencies. Verify pinout compatibility if considering alternative manufacturers' synchronous buck controllers. Confirm that replacement parts maintain the same 100 uA quiescent current specification and 300 kHz operating frequency.
