TD6810说明
TD6810是一款采用恒定频率,电流模式架构的高效率单片同步降压稳压器。TD6810装置是可调节的版本,1.5V和1.8V固定输出电压。操作过程中电源电流仅为20毫安和下降到≤1mA关断。 2.5V至5.5V的输入电压范围使得TD6810非常适合于单节锂离子电池供电的应用。 100%占空比提供了低压差操作,延长了便携式设备的电池寿命。自动突发模式工作提高了效率,在轻负载,从而进一步延长了电池的使用寿命。开关频率在内部设定为1.5MHz,允许使用小型表面贴装电感器和电容器。内部同步开关提高效率,并省去了一个外部肖特基二极管。低输出电压很容易与0.6V反馈参考电压支持。TD6810是低调(高度仅1mm)TSOT23-5封装。
TD6810 Description
The TD6810 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version and fixed output voltages of 1.5V and 1.8V. Supply current during operation is only 20mA and drops to ≤1mA in shutdown. The 2.5V to 5.5V input voltage range makes the TD6810 ideally suited for single Li-Ion battery-powered applications. *** duty cycle provides low dropout operation, extending battery life in portable systems.Automatic Burst Mode operation increases efficiency at light loads, further extending battery life.Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors.The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage. The TD6810 is available in a low profile (1mm) TSOT23-5 package.
