BD8960NV-E2

Overview

The BD8960NV-E2 is a synchronous buck converter from ROHM Semiconductor, designed for high-efficiency step-down regulation. It operates with an input voltage range of 2.7 V to 5.5 V and delivers a maximum output current of 2 A. The device supports adjustable output voltages between 1 V and 2.5 V. Key electrical specifications include a typical switching frequency of 1 MHz, a standby current of 10 uA, and an operating temperature range from -25°C to +105°C. It utilizes a SON-8 package.

Feature Summary

• Employs a current mode PWM control system to provide fast transient response to sudden load changes.
• Integrates N-channel and P-channel FETs for synchronous rectification, ensuring high efficiency across all load ranges.
• Includes built-in protection features such as thermal shutdown, under-voltage lockout (ULVO), and short-current protection with a time delay function.

Applications

• Power supply for DSPs
• Microcomputer power systems
• ASIC power delivery

Procurement Notes

Verify the component status before procurement, as this part may be marked as Not Recommended for New Designs (NRND). Confirm that the SON-8 package dimensions align with your PCB footprint requirements. Ensure the input voltage source remains within the specified 2.7 V to 5.5 V range to guarantee proper operation and avoid triggering under-voltage lockout conditions during system integration.

Selection Notes

Select this component when designing systems requiring a wide input voltage range starting from 2.7 V, which accommodates single-cell lithium battery applications. It is suitable for designs needing a compact solution with integrated power FETs, eliminating the need for external high-current switches. Consider the -25°C minimum operating temperature limit when evaluating environmental constraints compared to industrial-grade alternatives that support lower temperatures.
