General Description

MIC27600은 고유한 디지털 수정 적응형 정시 제어 아키텍처를 특징으로 하는 정주파수, 동기식 벅 레귤레이터입니다. MIC27600은 4.5V ~ 36V의 입력 공급 범위에서 작동하고 최대 7A의 출력 전류로 조정된 출력을 제공합니다. 출력 전압은 ±1%의 보장된 정확도로 0.8V까지 조정 가능하며 장치는 300kHz의 스위칭 주파수에서 작동합니다.

Hyper Speed ​​Control™ 아키텍처는 출력 커패시턴스를 줄이는 동시에 초고속 과도 응답을 허용하고 (High VIN)/(Low VOUT) 작동도 가능하게 합니다. 디지털 방식으로 수정된 이 적응형 tON 리플 제어 아키텍처는 고정 주파수 작동과 빠른 과도 응답의 장점을 단일 장치에 결합합니다.

MIC27600은 오류 조건 동안 IC를 보호하기 위해 전체 보호 기능 제품군을 제공합니다. 여기에는 전력 저하 조건에서 적절한 작동을 보장하기 위한 저전압 잠금, 돌입 전류를 줄이기 위한 내부 소프트 스타트, 폴드백 전류 제한, "히컵" 모드 단락 회로 보호 및 열 차단이 포함됩니다.

구하라 그리하면 너희에게 주실 것이요 

찾으라 그리하면 찾아낼 것이요 

문을 두드리라 그리하면 너희에게 열릴 것이니

구하는 이마다 받을 것이요 

찾는 이는 찾아낼 것이요 

두드리는 이에게는 열릴 것이니라

-마태복음 6장 7,8절
