NOTE:This is a new LM2577

DC:IN3.5-30V
          OUT 4.0-30V
In+:Input positive
In-:Input negative
Out+:Output positive
Out-:Output negative
Size: 44x30x14 (length*width*height)(mm)
Color: As the picture show
Weight: 15g
Input voltage: 3.5-30V
LED Indicator : YES
Output voltage: 4-30V(Adjustable)
Input current: Rated current is 2A maximum 3A (Additional heat sink is required)
Load Regulation: ±0.5
Voltage Regulation: ±0.5%
Module Properties: Non-isolated step-Up module
Switching Frequency: 52kHz
Full load Temperature rise: 40 degree
Dynamic Response speed: 5% 200u
重 量:15克
外 觀 尺 寸 :44mm*30mm*14mm(長*寬*高)
輸入電壓範圍:3.5V-30V(必須保證設定輸出電壓高於輸入電壓)
輸出電壓範圍:4.0V-30V
輸入最大電流:3A(根據功率守恆計算額定條件下的輸出電流Uin*Iin*效率=Uout*Iout)
輸入連續工作電流:2A(通風散熱條件良好輸出電壓和輸入電壓之比不能大於3)
IN+輸入正極
IN-
輸入負極
OUT+
輸出正極
OUT-輸出負極

工作效率測試如下:

5V轉12V:


5V轉12V=(11.93*0.500)/(5.02*1.383)*100%=86.3%(由於測試沒考慮線上壓降實際輸出效率優於測試效率)

12V轉24V:



12V轉24V=(23.84*0.799)/(12.03*1.747)*100%=90.7%(由於測試沒考慮線上壓降實際輸出效率優於測試效率)

全新升級改版》》》》》增加工作指示燈讓模塊工作狀態一幕了然!

典型應用:

1、3.7轉5V做行動電源

2、升壓驅動LED燈串(需要增加合適的限流電阻)

3、7.4V升壓12V應用在航模攝像頭

注意:大電流工作時會大量發熱請注意加強通風散熱。
