描述 Description
The STI8021 is a 1.5MHz constant frequency current mode,dual-channel high-efficiency PWM step-down converter.It is ideal for portable equipment requiring very high current up to 1.2A each channel from single-cell Lithium-ion batteries while still achieving over 90%efficiency during peak load conditions.The STI8021 also can run at 100%duty cycle for low dropout operation,extending battery life in portable systems while light load operation provides very low output ripple for noise sensitive applications.The STI8021 can supply up to 1.2A output load current each channel from a 2.5V to 5.5V input voltage and the output voltage can be regulated as low as 0.6V.The internal slope compensation setting allows the device to operate with smaller inductor values to optimize size and provide efficient operation.The output voltage of STI8021 is available in adjustable from 0.6V to VIN.The device is available in a Pb-free,DFN3*3-10 package and is rated over the-40°C to+85°C temperature range.Operation modes,PWM control and PFM Mode switching control,allow a high efficiency over the wider range of the load.
