BD9528AMUV
Description
BD9528AMUV is a 2ch switching regulator controller with high output current which can achieve low output voltage (1.0V～ 5.5V) from a wide input voltage range (5.5V～28V). High efficiency for the switching regulator can be realized by utilizing an 3 TM external N-MOSFET power transistor. A new technology called H Reg (High speed, High efficiency, High performance) is a Rohm proprietary control method to realize ultra high transient response against load change. SLLM (Simple Light Load Mode) technology is also integrated to improve efficiency in light load mode, providing high efficiency over a wide load range. For protection and ease of use, 2ch LDO (5V/3.3V (total 100m A)), the soft start function, variable frequency function, short circuit protection function with timer latch, over voltage protection, and Power good function are all built in. This switching regulator is specially designed for Main Power Supply of laptop PC.
