The BU90004GWZ-E2 from ROHM Semiconductor is a synchronous buck DC-DC converter designed for efficient power management in portable applications. This device features integrated 250mΩ high-side Pch and 220mΩ low-side Nch MOSFETs, enabling a compact solution.
Key electrical specifications include an input voltage range of 2.3V to 5.5V, a fixed 1.8V output voltage, and a maximum output current of 1A. The converter operates at a switching frequency of 5.4MHz, with a range of 4.8MHz to 6.0MHz, allowing for small external components. It incorporates multiple protection functions such as soft start, UVLO (Under Voltage Lock Out), TSD (Thermal Shutdown), and OCP (Over Current Protection).
The BU90004GWZ-E2 supports flexible operation with an EN pin for ON/OFF control and a MODE pin for selecting between fixed PWM operation or automatic PFM/PWM switching to optimize efficiency under light loads. The device is housed in a 6-WLCSP package, suitable for surface mount applications.
This converter is well-suited for applications such as smartphones, portables, compact DC-DC modules, and USB accessories where space and power efficiency are critical.
