BU90007GWZ-E2

Overview

The BU90007GWZ-E2 is a synchronous buck switching regulator IC from ROHM Semiconductor, featuring an integrated power FET. It operates within an input voltage range of 2.3 V to 5.5 V and provides a fixed output voltage of 1.25 V with a maximum output current of 1 A. The device supports a switching frequency between 3.6 MHz and 4.4 MHz and maintains a typical quiescent current of 45 uA. Designed for surface-mount installation in a UCSP35L1-6 package, it functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

Integrates a synchronous rectifier controller and power FET for high efficiency.
Supports automatic PFM/PWM operation for optimized light-load performance.
Includes internal soft start and under-voltage lockout protection mechanisms.

Applications

Portable electronic devices requiring compact power solutions
Embedded systems utilizing low-voltage logic levels
Battery-powered consumer electronics

Procurement Notes

Verify component authenticity through authorized channels due to potential supply chain variations. Confirm that the specific suffix matches the required RoHS compliance and packaging format. Check for end-of-life status or obsolescence notices before finalizing procurement plans. Ensure storage conditions adhere to moisture sensitivity level requirements for the UCSP35L1-6 package to prevent soldering defects during assembly.

Selection Notes

Select this component when a fixed 1.25 V output is required without external feedback resistors. The integrated FET design reduces external component count compared to discrete solutions. Consider the 4.4 MHz switching frequency for minimizing passive component sizes. Verify that the load current does not exceed the 1 A limit and that the input voltage remains within the specified 2.3 V to 5.5 V window for stable regulation.

Part Context

This part belongs to the BU90007GWZ series of step-down switching regulators. It is categorized under PMIC - Power Management ICs. The manufacturer is ROHM Semiconductor. The product status indicates it may be subject to discontinuation or limited availability depending on the region.
