Its application circuit is very simple, which only needs two outside capacitors. We have to take heat dissipation into great consideration when voltage of input is high. Because in such cases, the power dissipation consumed by BL8065 is very large. BL8065 uses SOT-89-3 package type and its thermal resistance is about 20°C/W. And the copper area of application board can affect the total thermal resistance. If copper area is 5cm*5cm (two sides), the resistance is about 30°C/W. So the total thermal resistance is about 20°C/W + 30°C/W. We can decrease total thermal resistance by increasing copper area in application board. When there is no good heat dissipation copper are in PCB, the total thermal resistance will be as high as 120°C/W, then the power dissipation of BL8065 could allow on itself is less than 1W. And furthermore, BL8065 will work at junction temperature higher than 125°C under such condition and no lifetime is guaranteed. www.belling.com.cn 4 BL8065 TYPICAL PERFORMANCE CHARACTERISTICS (T=25°C unless specified.)
