BD9A100MUV
2.7V to 5.5V Input, 1A Integrated MOSFET Single Synchronous Buck DC/DC Converter
BD9A100MUV
2.7V to 5.5V Input, 1A Integrated MOSFET Single Synchronous Buck DC/DC Converter
BD9A100MUV is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. It is capable of providing current up to 1A.The SLLM™ control provides excellent efficiency characteristics in light-load conditions which make the product ideal for equipment and devices that demand minimal standby power consumption. The oscillating frequency is high at 1MHz using a small value of inductance. It is a current mode control DC/DC converter and features high-speed transient response. Phase compensation can also be set easily.
