MAX77505 - 16V Input, 4.6A Switching Current Low IQ Buck Converter 

 

Analog devices

 

Description

The MAX77505 is a low-quiescent current (800nA typ), high-efficiency hysteretic buck converter operating from a 2.5V to 16V input voltage range. The device offers high efficiency over the entire load range. Hence, it is ideal for either a primary battery or four alkaline battery powered applications, which require long standby/idling time with short working time, such as asset tracking and door-lock devices.

A resistor (RSEL) selects one of thirty preset output voltages between 0.8V and 5.5V. The device has input undervoltage lockout, cycle-by-cycle switch current limit, and thermal shutdown to protect the system and the device itself. The device is available in a 10-lead FC2QFN package (2.0mm x 2.0mm x 0.55mm).

 

MAX77505는 낮은 대기 전류(typ 800nA)와 고효율을 자랑하는 히스테리틱 벅 컨버터로, 2.5V에서 16V의 입력 전압 범위에서 동작합니다. 이 장치는 전체 부하 범위에서 높은 효율을 제공하며, 장시간 대기 상태가 필요하고 짧은 작업 시간이 요구되는 자산 추적 장치나 도어락과 같은 1차 배터리 또는 4개의 알카라인 배터리로 구동되는 애플리케이션에 적합합니다.

저항(RSEL)을 통해 0.8V에서 5.5V 사이의 30가지 미리 설정된 출력 전압 중 하나를 선택할 수 있습니다. 이 장치는 시스템과 장치 자체를 보호하기 위해 입력 저전압 차단, 주기별 전류 제한, 열 차단 기능을 갖추고 있습니다. 이 제품은 2.0mm x 2.0mm x 0.55mm 크기의 10핀 FC2QFN 패키지로 제공됩니다.

악인은 그의 길을, 불의한 자는 그의 생각을 버리고 

여호와께로 돌아오라 

그리하면 그가 긍휼히 여기시리라 

우리 하나님께로 돌아오라 

그가 너그럽게 용서하시리라
