供应 TPS563201DDCR 降压稳压器

TPS563201是采用小外形尺寸晶体管 (SOT)-23 封装的简单易用型 3A 同步降压转换器。器件均经过优化，大限度地减少了运行所需的外部组件并且可以实现低待机电流。这些开关模式电源 (SMPS) 器件采用 D-CAP2 模式控制，能够提供快速瞬态响应，并且在无需外部补偿组件的情况下支持诸如高分子聚合物等低等效串联电阻 (ESR) 输出电容以及超低 ESR 陶瓷电容器。
TPS563201 可在脉冲跳跃模式下运行，从而能在轻载运行期间保持高效率。TPS563201 采用 6 引脚 1.6mm × 2.9mm SOT (DDC) 封装，额定结温范围为 –40°C 至 125°C。

Tps563201 is a simple and easy-to-use 3A synchronous buck converter with small size transistor (SOT) - 23 

package.The devices are optimized to minimize the number of external components required for operation 

and to achieve low standby current.

These SMPS devices are controlled by d-cap2 mode, which can provide fast transient response and support 

low equivalent series resistance (ESR) output capacitors such as polymer and ultra-low ESR ceramic 

capacitors without external compensation components.

The tps563201 operates in pulse skip mode to maintain high efficiency during light load operation. 

Tps563201 adopts 6-pin 1.6mm × 2.9mm sot (DDC) package with rated junction temperature range 

of – 40 ℃ ° C to 125 ° C。
