特性
- 调节VOUT高于、低于或等于VIN
- 单个电感
- 宽VIN范围:2.2V至40V
- 宽VOUT范围:2.7V至40V
- 输出电流:1A(降压模式下)
- 0.5A输出电流,VIN = 3.6V,VOUT = 5V
- 可编程平均输出电流
- 效率高达96%
LTC®3114-1 是一款通用的宽工作电压范围同步单片式降压-升压型 DC/DC 转换器,其具有可编程平均输出电流。LTC3114-1 的专有降压-升压型 PWM 控制电路可在整个工作电压范围内提供低噪声操作。电流模式控制确保了优异的电压和负载瞬态响应。
同步、内部 MOSFET 开关和引脚可选的突发模式操作可在整个负载电流范围内保持高效率。平均输出电流利用一个标准电阻器进行设置,并为实现宽输入范围、高效率充电系统或恒定电流、高效率 LED 驱动器提供了基础。稳压器接通可通过准确的 RUN 引脚进行编程。在停机模式中静态电流仅为 3μA。该器件集成了过热保护、短路保护和软起动功能。LTC3114-1 采用16 引脚 3mm x 5mm x 0.75mm DFN 封装和 16 引脚 TSSOP (FE) 封装。
应用
- 24V / 28V 工业电源
- 12V 铅酸电池至 12V 稳压器
- 高功率 LED 驱动器
- 12V / 24V 太阳能电池板电池充电系统

DC1821B
LTC3114EDHC-1 Demo Board | Sync Buck-Boost, VIN=2.7V to 40V, VOUT = 5V @ Up to 1A
产品详情
Demonstration circuit 1821B features the LTC3114-1, a wide operating range synchronous monolithic buck-boost converter with programmable average output current. DC1821B operates with a 2.7V to 40V input voltage range. The demo board has been designed with the output voltage set to 5V and can provide up to 1A output with VIN > 6V. It features two user selectable operating modes: Burst Mode® operation and Fixed Frequency PWM (JP2). There is also an accurate programmable RUN pin which is used to ENABLE the converter (JP1).
The LTC3114-1 uses average current mode control to simplify voltage loop compensation and provide good line and load transient response. It incorporates a proprietary low noise switching algorithm which optimizes efficiency with input voltages above, below or equal to the output voltage and ensures seamless transitions between operating modes.

SCP-LTC3114-1-EVALZ
LTC3114 信号链评估板| 具有可编程输出电流的 40V、1A 同步降压-升压型 DC/DC 转换器
产品详情
演示电路 SCP-LTC3114-1-EVALZ 配有 LTC3114-1,该套件是宽工作范围、同步单片降压-升压转换器,具有可编程的平均输出电流。该电路的输入电压范围为 2.2V 至 40V。
像信号链电源系列中的所有电路板一样,该板可轻松插入其他 SCP 板中,以形成完整的信号链电源系统,从而能够快速评估低功耗信号链。要评估该评估板,需要一些通用的 SCP 硬件,即:
- SCP-INPUT-EVALZ
- SCP-OUTPUT-EVALZ
- SCP-1X5BKOUT-EVALZ
- SCP-THRUBRD-EVALZ
- SCP-FILTER-EVALZ
- SCP-1X2BKOUT-EVALZ
- SCP-5X1-EVALZ
为了正确评估 SCP 系列演示板,您将需要 SCP Configurator 配套软件。SCP Configurator 可以帮助您为您的设计选择正确的电路板和拓扑。
请注意,演示手册并未涵盖关于 LTC3114-1 的操作和配置的重要细节。有关该套件的完整说明,请参考 LTC3114-1 数据手册。
