BU90005GWZ-E2 Description

Short technical summary and product information.

The BU90005GWZ-E2 from ROHM Semiconductor is a synchronous buck DC/DC converter designed for efficient power regulation. It operates with an input voltage range from 2.3V to 5.5V, delivering a stable 2.5V output with a maximum current of 1A. The converter utilizes integrated FETs and operates at a switching frequency between 5.4MHz and 6.6MHz.

 

This device includes multiple protection functions such as soft start, UVLO (Under Voltage Lock Out), TSD (Thermal Shutdown), and OCP (Over Current Protection). An EN pin allows for simple ON/OFF control, and a MODE pin enables selection between fixed PWM or PFM operation for improved light-load efficiency.

 

The BU90005GWZ-E2 is suitable for applications like smartphones, portables, and compact DC/DC modules. It is available in a compact 6-WLCSP package, suitable for surface mount applications.

 

Key electrical specifications include a 2.3V to 5.5V supply voltage, a fixed 2.5V output voltage, and a maximum output current of 1A. The switching frequency is typically around 6MHz.
