DC1144A-A

LT3580EDD 演示板 | 3V ≤ VIN ≤ 10V,VOUT = 12V (在 300mA)

产品详情

演示电路 1144A-A 和 1144A-B 具有分别采用升压和负输出稳压器配置的 LT3580EDD。这些演示电路拥有尺寸小巧和组件数少的特点。DC1144A-A 设计用于将 3V 至 10V 电源转换为 12V/300mA 输出,而 DC1144A-B 负输出转换器则专为将 5V 至 12V 电源转换为 -12V/350mA 输出而设计。


LT3580 可在输入高达 32V 的条件下工作,但是在这些演示板中,输入受限于输入电容器的额定电压和升压输出的幅值。DC1146A-B 可以容易地配置成 SEPIC 转换器。

LT3580EDD Demo Board | 5V ≤ VIN ≤ 12, VOUT = -12V @ 350mA

产品详情

Demonstration circuits 1144A-A and 1144A-B feature the LT3580EDD in Boost and Inverting regulator configurations, respectively. The demo circuits demonstrate small size and low component count. The DC1144A-A is designed to convert a 3V to 10V source to 12V at 300mA, while the DC1144A-B inverter converts a 5V to 12V source to -12V at 350mA.


The LT3580 operates with inputs as high as 32V but in these demo boards the input is limited by the voltage rating of the input capacitors and the magnitude of the boost output. The DC1146A-B can easily be configured into a SEPIC converter.
