반응형

RTQ2131B-QA - 1A, 36V, 2.1MHz Synchronous Step-Down Converter

 

RICHTEK

 

General Description

RTQ2131B는 3V ~ 36V의 폭넓은 입력 전원에서 최대 1A의 출력 전류를 제공할 수 있는 고효율 모놀리식 동기식 강압 DC-DC 컨버터입니다. 외부 보상 기능이 있는 RTQ2131B 전류 모드 제어를 통해 다양한 부하 및 출력 커패시터에서 과도 응답을 최적화할 수 있습니다. 사이클별 전류 제한은 단락 출력에 대한 보호를 제공하고 소프트 스타트는 스타트업 중 입력 전류 서지를 제거할 수 있습니다. 입력 저전압 잠금, 출력 저전압 보호, 과전류 보호 및 과열 보호는 적용된 모든 조건에서 완전히 안전하고 부드러운 작동을 제공합니다. RTQ2131B는 TA = -40°C ~ 125°C의 온도 범위에서 완전히 지정되었으며 WDFN-10SL 3x3 패키지로 제공됩니다.
