Hi-performance Regulator IC Series for PCs

Switching Regulators

for DDR-SDRAM Cores

BD9575FV

No.09030EBT11

●Description

BD9575FV 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

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

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=200KHz½600KHz)

6) SSOP-B20 Package

●Applications

Laptop PC, Desktop PC, LCD-TV, Digital Components

●Maximum

Absolute Ratings (Ta=25℃)
