评估板, 降压DC/DC 转换器, 2.7V-5.5V输入, 1.0A 输出电流
The 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.
