BD9A101MUV-EVK-001

The BD9A101MUV-EVK-001 from ROHM is a step-down DC/DC converter BD9A101MUV-LB evaluation board. The BD9A101MUV-LB is a single synchronous buck switching regulator with built-in low on-resistance power MOSFETs in VQFN016V3030 package (backside heat dissipation). The IC has internal 60mohm high-side N-channel MOSFET and 60mohm low side N-channel MOSFET and a synchronization frequency is of 1MHz. A soft start circuit prevents in-rush current during start-up. 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 frequency PWM mode or enables the light load mode control and the mode is automatically switched between the light load mode control and fixed frequency PWM mode. Include OCP (over current protection) and SCP (short circuit protection).

• Supply voltage range from 2.7V to 5.5V, DC power-supply presets to 5V then power output turns off
• Output voltage of 1.8V
• Output current of 1A, the maximum load should be set at 1A and over it will be disabled
• Connect +ve terminal of power-supply to VIN+ and -ve terminal to GND-terminal with a pair of wires
• Connect load’s +ve terminal to VOUT+ terminal and -ve terminal to GND-terminal with a pair of wires
• Long time support product for industrial application
