描述
The BD93291EFJ is a dual synchronous buck converter. It integrates wide input voltage range (8.0V to 26V) synchronous buck converter and low input voltage (Vout1 : 5.0V) synchronous buck converter. The IC also incorporates a new technology called H3RegTM, a Rohm proprietary control method which facilitates ultra-high transient response against changes in load. SLLM (Simple Light Load Mode) technology is also integrated to improve efficiency when powering lighter loads. For protection and ease of use, the IC also incorporates soft start. Space-saving and high efficient switching regulator can be achieved due to built-in N-MOSFET power transistor in HTSOP-J8 package.

Dual Synchronous Buck Converter

BD93291EFJ

●Description

The BD93291EFJ is a dual synchronous buck converter.

It integrates wide input voltage range (8.0V to 26V) synchronous

buck converter and low input voltage (Vout1 : 5.0V)

synchronous buck converter.

●Features

・Dual Synchronous Buck Converter in small package.

・standby mode ( Istandby = 0uA )

・High Voltage Synchronous Buck Converter(Vout1)

The IC also incorporates a new technology called

H³Reg^TM, a Rohm proprietary control method which

facilitates ultra-high transient response against changes in

load. SLLM (Simple Light Load Mode) technology is also

integrated to improve efficiency when powering lighter

loads. For protection and ease of use, the IC also

incorporates soft start.

Space-saving and high efficient switching regulator can be

achieved due to built-in N-MOSFET power transistor in

HTSOP-J8 package.
