TPS61200DRCTG4

illustrate

The TPS6120x device provides a power solution for products powered by a single-cell, two-cell, or three-cell alkaline, nickel-cadmium or nickel-metal hydride battery, or a single-cell lithium-ion or lithium-polymer battery. It can also be used in fuel cells or solar cells, where the ability to handle low input voltages is essential. The possible output current depends on the output voltage ratio to the input. 这些器件提供了输出电流为600毫安培在5 - V的输出，同时使用单节锂离子或锂聚合物电池，并将其释放到2.5 V的升压转换器是一个固定的频率为基础，脉冲脉宽调制（PWM）控制器采用同步整流技术获得最大的效益。 At low load currents, the converter enters power-down mode to maintain high efficiency over a wide load current range.
