This evaluation board has been developed for ROHM’s synchronous buck DC/DC converter customers evaluatingBD9B300MUV. While accepting a power supply of 2.7-5.5V, an output of 3.3V can be produced. The IC has internal 35mΩhigh-side P-channel MOSFET and 35mΩ low-side N-channel MOSFET and a synchronization frequency is of 1MHz (FREQ pinis connected to VIN) or 2MHz (FREQ pin is connected to ground). A fixed Soft Start circuit prevents in-rush current during startupalong with UVLO (Under Voltage Lockout) and TSD (Thermal Shutdown) protection circuits. An EN pin allows for simpleON/OFF control of the IC to reduce standby current consumption. A MODE pin allows the user to select fixed frequency PWMmode or enables the Deep-SLLM control and the mode is automatically switched between the Deep-SLLM control and fixedfrequency PWM mode.
