[ Product description ]

BD9532EKN is a switching regulator controller with high output current which can achieve low output voltage (0.7V to 2.0V) from a wide input voltage range (4.5V to 25V). High efficiency for the switching regulator can be realized by utilizing an external N-MOSFET power transistor. A new technology called H³Reg^TM 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, the soft start function, variable frequency function, short circuit protection function with timer latch, and REF synchronous function are all built in. This switching regulator is specially designed for the DDR-SDRAM core.
