Innovision Semiconductor Inc IS66066

Description

The IS66066 is a high power density, fully integrated synchronous buck converter. It has wide input voltage range and can support up to 12A continuous output current at defined conditions. LDO is integrated internally, which is very suitable for single input supply condition. External bias is optional for maximizing the efficiency. A differential sensing scheme and a 0.6V internal feedback reference voltage achieve ±1% tolerance over full temperature range and perform an excellent line and load regulation.Switching frequency can be easily adjusted among 600 kHz, 800 kHz and 1 MHz. The IS66066 uses patented Turbo Constant On Time (TCOTTM) to control the algorithm with fast transient response. Pure MLCC output capacitors can be used to save space and cost.
