AAT1106数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The AAT1106 is a 1.5MHz constant frequency current mode PWM step-down SwitchReg™ converter with a unique adaptive slope compensation scheme allowing the device to operate with a lower range of inductor values to optimize size and provide efficient operation. It is ideal for portable equipment powered by single-cell Lithium-ion batteries and is optimized for high efficiency, achieving levels up to 96%.
The AAT1106 can supply up to 600mA load current from a 2.5V to 5.5V input voltage and the output voltage can be regulated as low as 0.6V. The device also can run at 100% duty cycle for low dropout operation, extending battery life in portable systems. In addition, light load operation provides very low output ripple for noise sensitive applications and the 1.5MHz switching frequency minimizes the size of external components while keeping switching losses low.
The AAT1106 is available in a Pb-free, low-profile 5-pin TSOT23 package, and is rated over the -40°C to +85°C temperature range.
