Description
BD9535MUV is a 2ch switching regulator controller with high output current which can achieve low output voltage (0.7V～ 2.0V) from a wide input voltage range (4.5V～ 25V). High efficiency for the switching regulator can be realized by utilizing an external N-MOSFET power transistor. A new technology called H3RegTM is a Rohm proprietary control method to realize ultra high transient response against load change. SLLMTM (Simple Light Load Mode) technology is also integrated to improve efficiency in light load mode, providing high efficiency over a wide load range. For the soft start/stop function, variable frequency function, short circuit protection function with timer latch, and tracking function are all built in. This 2ch switching regulator is specially designed for Chipset and Front Side Bus.
