TECHNICAL NOTE
High-performance Regulator IC Series for PCs
Switching Regulators
for DDR-SDRAM Cores
BD9533EKN
● Description
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 H Reg
3 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, over voltage protection function and
REF synchronous function are all built in. This switching regulator is specially designed for the DDR-SDRAM core.
● Features
1) H Reg
3 TM
Switching Regulator Controller
2) Light Load Mode and Continuous Mode Changeable
3) Thermal Shut Down (TSD), Under Voltage LockOut (UVLO), Over Current Protection (OCP),
Over Voltage Protection (OVP), Short Circuit Protection (SCP) built-in
4) Soft start function to minimize rush current during startup
5) Switching Frequency Variable (f=200KHz ～ 600KHz)
6) HQFN20V Package
● Applications
Laptop PC, Desktop PC, LCD-TV, Digital Components
