BD95602MUV-LBE2

Overview

The BD95602MUV-LBE2 is a dual-channel synchronous buck DC/DC controller from ROHM Semiconductor, designed for industrial equipment. It supports an input voltage range of 5.5V to 28V and provides two independent output channels with adjustable voltages between 1.0V and 5.5V. The device utilizes the H3reg™ control mode for fast transient response and SLLM™ for improved light-load efficiency. It integrates two LDOs (5V and 3.3V) with a total current capacity of 50mA. Key features include variable switching frequency up to 0.5MHz, soft-start functionality, and comprehensive protection circuits such as short-circuit protection with timer latch and overvoltage protection.

Feature Summary

• Employs H3reg™ constant time control mode for rapid transient response characteristics
• Integrates SLLM™ (Simple Light Load Mode) to enhance efficiency across a wide load current range
• Includes built-in dual LDOs (5V and 3.3V) providing a combined maximum output current of 50mA
• Features advanced protection mechanisms including timer-latch short-circuit protection and overvoltage protection

Applications

• Industrial equipment power supplies
• Xilinx Spartan-7 FPGA reference designs
• Systems requiring wide input voltage ranges with multiple low-voltage outputs

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix -LB indicates long-term support status for industrial applications. Check for RoHS compliance documentation. Ensure the VQFN032V5050 package matches your PCB footprint requirements. Validate that the operating temperature range meets your system's environmental specifications before finalizing procurement.

Selection Notes

Select this controller when designing systems requiring dual synchronous buck outputs from a wide input voltage range.
