BD95602MUV-E2

Overview

The BD95602MUV-E2 is a dual-channel synchronous buck DC/DC controller designed for industrial applications. It supports an input voltage range of 5.5V to 28V and delivers output voltages from 1.0V to 5.5V. The device integrates H3Reg™ control mode for fast transient response and SLLM™ for high efficiency at light loads. It includes two LDOs (5V/3.3V, total 50mA), soft-start, adjustable switching frequency up to 0.5MHz, and comprehensive protection features including short-circuit with timer latch and overvoltage protection.

Feature Summary

• Utilizes ROHM's proprietary H3Reg™ constant time control mode for rapid transient response without phase compensation components.
• Incorporates SLLM™ technology to maintain high conversion efficiency across a wide load current range during light-load conditions.
• Integrates two low-dropout regulators providing 5V and 3.3V outputs with a combined maximum current capacity of 50mA.

Applications

• Industrial equipment power supplies requiring stable operation under wide input voltage variations
• Systems utilizing Xilinx Spartan-7 FPGA architectures as documented in reference designs
• Applications demanding high-efficiency power management for large current loads

Procurement Notes

Verify the specific suffix 'E2' against the manufacturer's latest documentation to confirm environmental compliance and pin compatibility. Confirm that the VQFN032V5050 package dimensions match your PCB footprint requirements. Ensure the design accounts for the thermal dissipation characteristics associated with the bare pad on this surface-mount package.

Selection Notes

Select this component when a dual-channel solution is required within a 5.5V to 28V input window. It is suitable for designs needing integrated LDOs alongside switched outputs. Consider the H3Reg™ architecture if phase compensation complexity must be minimized. Verify that the 0.5MHz maximum switching frequency aligns with your electromagnetic interference constraints and inductor size limitations.

Part Context

This part belongs to the BD95602 series of multi-channel power management ICs from ROHM Semiconductor. It is specifically engineered for industrial markets with a focus on long-term supply stability. The device complements other controllers in the family by offering integrated LDOs and advanced light-load modes within a compact VQFN package.

Replacement Considerations

Consult official substitution lists for equivalent dual-channel buck controllers. Verify that any alternative maintains the 5.5V–28V input range and compatible pinout. Ensure the replacement supports similar transient response speeds and protection mechanisms such as timer-latched short-circuit protection.
