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 H³Reg^TMis 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) H³Reg^TMSwitching 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
