2.7V to 5.5V Input, 3A Integrated MOSFET Single Synchronous Buck DC/DC Converter - BD9A302QWZ (New)

BD9A302QWZ is a synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. This IC is capable of providing current up to 3A. 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 inductor. BD9A302QWZ is a current mode control DC/DC converter and features high-speed transient response. Phase compensation can also be set easily.
