BD9B300MUV-EVK-101: 3.3V @ 3A, 2.7 ~ 5.5V in

The BD9B300MUV-E2EVK-101 evaluation board has been developed for ROHM’s synchronous buck DC/DC converter customers evaluating BD9B300MUV. While accepting a power supply of 2.7-5.5V, an output of 3.3V can be produced. The IC has internal 35mΩ high-side P-channel MOSFET and 35mΩ low-side N-channel MOSFET and a synchronization frequency is of 1MHz (FREQ pin is connected to VIN) or 2MHz (FREQ pin is connected to ground). A fixed Soft Start circuit prevents in-rush current during startup along with UVLO (Under Voltage Lockout) and TSD (Thermal Shutdown) protection circuits. An EN pin allows for simple ON/OFF control of the IC to reduce standby current consumption. A MODE pin allows the user to select fixed requency PWM mode or enables the Deep-SLLM control and the mode is automatically switched between the Deep-SLLM control and fixed frequency PWM mode.
