ROHM BD9533EKN handbook
BD9533EKN 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 28V). 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. 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, over voltage protection function and REF synchronous function are all built in. This switching regulator is specially designed for the DDR-SDRAM core.

ROHM BD95514MUV handbook
BD95514MUV is a switching regulator capable of supplying high current output (up to 4A) at low output voltages (0.7V~5.0V) over a broad range of input voltages (4.5V~28V). The regulator features an internal N-MOSFET power transistor for high efficiency and low space consumption, while incorporating ROHM’s proprietary H3RegTM control mode technology, yielding the industry’s fastest transient response time against load changes. SLLM (Simple Light Load Mode) technology is also integrated to improve efficiency when powering lighter loads, as well as soft start, variable frequency, short-circuit protection with timer latch, over-voltage protection, and REF tracking functions. This regulator is suited for PC applications.
