Overview
The BD9E303EFJ-LBE2 is a synchronous buck DC/DC converter from ROHM, designed for industrial applications. It features an input voltage range of 7V to 36V and delivers a maximum output current of 3A. The adjustable output voltage spans from 1V to 28.8V. Operating with a maximum switching frequency of 345kHz, it utilizes current-mode control for fast transient response. The device is housed in an 8-pin HTSOP-J package with dimensions of 4.9mm x 3.9mm x 0.85mm. It supports a junction temperature range from -40°C to 150°C.
Feature Summary
- Integrates low on-resistance power MOSFETs within a synchronous rectification topology.
Applications
- Industrial equipment power supplies
Procurement Notes
Verify the specific suffix LB(E2) against the manufacturer's latest documentation to confirm pinout and electrical specifications. Check for any pending Product Change Notices (PCN) that may update mechanical or material specifications without altering electrical performance. Ensure the ordering quantity aligns with the standard taping packaging requirements specified by the supplier.
Selection Notes
Select this component when a wide input voltage range up to 36V is required alongside a 3A output capability. The integrated MOSFET design simplifies the bill of materials compared to discrete solutions. Current-mode control facilitates easier phase compensation setup. Verify that the thermal management strategy accommodates the HTSOP-J package constraints for the intended load conditions.
Part Context
This part belongs to the BD9E303EFJ series of synchronous buck converters. These devices are positioned as long-term supply products for the industrial market. They utilize a constant on-time control method to achieve high efficiency at light loads and fast transient responses, distinguishing them from fixed-frequency PWM controllers.
Replacement Considerations
BD9E300EFJ-LBE2 offers similar functionality but with a lower 2.5A output current rating. Both parts share the same HTSOP-J-8 package and input voltage range, allowing for potential pin-compatible substitution if the load current does not exceed 2.5A.
