Overview
The BD9C601EFJ-E2 is a synchronous buck DC-DC converter manufactured by ROHM Semiconductor. It integrates a low on-resistance power MOSFET to deliver a maximum output current of 6A. The device operates with an input voltage range from 4.5V to 18V and provides an adjustable output voltage between 800mV and 12.6V. It utilizes a constant on-time control method for fast transient response and features a switching frequency of 500kHz. The component supports shutdown functionality, has a static current of 10uA, and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a low on-resistance power MOSFET for high efficiency in a single chip solution.
- Employs constant on-time control architecture to ensure rapid load transient response.
- Supports wide input voltage ranges suitable for various system power rails.
Applications
- General purpose DC/DC conversion for industrial equipment
- Power supply stages for consumer electronics devices
- Secondary side power regulation in compact systems
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm package details and compliance status. Ensure the ordering code matches the required tape and reel quantity. Cross-reference the RoHS declaration directly with official documentation before finalizing procurement orders.
Selection Notes
Select this component when a 6A output capability is required within an 18V input limit. The integrated MOSFET design reduces external component count compared to discrete solutions. Consider the HTSOP-J8 package constraints for thermal management in dense PCB layouts.
Part Context
This part belongs to the BD9Cxxx series of synchronous buck converters from ROHM. These ICs are designed for applications requiring high current density and simple phase compensation. The series emphasizes low standby power consumption through optimized control methods.
Replacement Considerations
The BD9C601EFJ is listed as a related part number alias. Verify if the non-E2 suffix variant meets all electrical and packaging requirements for the specific application design.
