BU9000xGWZEVK-101 DC/DC Converter Evaluation Board

ROHM BU9000xGWZEVK-101 DC/DC Converter Evaluation Boards have been developed for evaluating the BU90002GWZ synchronous buck DC/DC converter. The BU9000xGWZEVK-101 accepts a power supply of 4.0-5.5V, and an output of 3.3V can be produced. The IC has an internal 250mΩ high-side P-channel MOSFET and 220mΩ low-side N-channel MOSFET and a synchronization frequency range of 5.4MHz to 6.6MHz. A fixed Soft Start circuit in the ROHM BU9000xGWZEVK-101 prevents inrush current during startup and UVLO (low voltage error prevention circuit) and TSD (thermal shutdown detection) protection circuits. An EN pin allows for simple ON/OFF control of the IC to reduce standby current consumption. A MODE pin allows selection of Forced PWM (Pulse Width Modulation) mode or PFM (Pulse Frequency Modulation). PWM auto-change mode utilizes power save operation at light load currents.
