LT3757AEDD Boost Demo Board | Boost, 3.1V ≤ VIN ≤ 9V; VOUT = 12V at 1.5A

立即购买更多内容

产品详情

Demonstration circuit 1547B features the LT3757AEDD in a 400kHz BOOST converter circuit, designed for a 12V output from a 3.1V to 9V input voltage range.

The LT3757A operates over an input range of 2.9V to 40V, suitable for applications from single-cell lithium-ion battery portable electronics up to high voltage automotive and industrial power supplies. It also exhibits low shutdown quiescent current of 1μA, making them an ideal fit for battery-operated systems. Thanks to a novel FBX pin architecture, the LT3757A can be connected directly to a divider from either the positive output or the negative output to ground. The LT3757A has improved load transient performance compared to the LT3757.

Demonstration circuit 1548A features the LT3757EDD in a 300kHz CUK converter circuit, designed for −15V output from a 7V to 28V input. The LT3757EDD operates over an input range of 2.9V to 40V, suitable for applications from single-cell lithium-ion battery portable electronics up to high voltage automotive and industrial power supplies. It also exhibits low shutdown quiescent current of 1μA, making them an ideal fit for battery-operated systems. Thanks to a novel FBX pin architecture, the LT3757EDD can be connected directly to a divider from either the positive output or the negative output to ground. It also packs many popular features such as soft-start, input undervoltage lockout, adjustable frequency and synchronization in a small 10-lead MSOP package or a 3mm × 3mm QFN package.

产品详情

演示电路1341A在300kHz SEPIC转换器电路中内置LT3757EDD，旨在通过4.5V至36V输入提供5V输出电压。

LT3757EDD在2.9V至40V的输入电压范围内工作，适合单节锂离子电池便携式电子设备到高压汽车和工业电源应用。它还具有1µA的低关断静态电流，使其非常适合电池供电系统。该IC集成了高压、低压差线性(LDO)稳压器。得益于创新的FBX引脚架构，LT3757EDD可从正输出或负输出到地直接连接到分频器。它们还提供许多常见功能，如软启动、输入欠压保护、可调频率和同步，采用小型10引脚MSOP封装或3mm × 3mm QFN封装。
