Overview
The BD9303FP-E2 is a switching voltage regulator manufactured by ROHM Semiconductor. It operates as a power switch regulator with an integrated switching frequency of 1 MHz and supports an output current of 2 A. The device belongs to the BD9303FP series and falls under the PMIC - Power Management ICs subcategory. It is classified as a Switching Voltage Regulator type. The component is currently listed as End-of-Life (EOL) or discontinued, with specific discontinuance notifications available from the manufacturer.
Feature Summary
- Integrated power switch regulator topology
- High-frequency operation at 1 MHz for compact external component sizing
- Capable of delivering up to 2 A output current
Applications
- General purpose DC-DC conversion in portable electronics
- Power supply stages in industrial control systems
- Battery-powered devices requiring efficient voltage regulation
Procurement Notes
Verify availability status carefully as this part is marked as End-of-Life (EOL). Check for official discontinuance notifications from ROHM Semiconductor before finalizing design-in decisions. Confirm that existing stock or last-time-buy options meet project timelines. Ensure alternative components are identified if long-term supply is required for new production runs.
Selection Notes
Select this component only for legacy system maintenance or repair where original specifications must be maintained. Evaluate the 1 MHz switching frequency against electromagnetic interference (EMI) constraints in the target application. Consider the 2 A output capability relative to peak load requirements. Assess thermal management needs given the package type and power dissipation characteristics inherent to this regulator class.
Part Context
This component is part of the BD9303FP series from ROHM Semiconductor, designed for efficient power management in compact electronic designs. It integrates a power switch and control logic into a single package to reduce board space. The series targets applications requiring moderate current levels with high efficiency. As a switching regulator, it converts input voltage to a stable output level suitable for powering sensitive downstream circuitry.
Replacement Considerations
Publicly confirmed substitute part numbers are not explicitly listed in the provided documentation. Consult ROHM Semiconductor's official replacement guide or distributor cross-reference tools for verified alternatives. Ensure any substitute matches the 2 A output current, 1 MHz frequency, and compatible pinout if direct replacement is intended.
