Innovision Semiconductor Inc IS6607A

Description

The IS6607A is a high power density, fully integrated synchronous buck converter. It works with wide input voltage range and can support up to 20A 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% output voltage tolerance over full temperature range. The IS6607A provides excellent line and load regulation.Switching frequency can be easily programmed among 600kHz, 800kHz and 1MHz. The IS6607A 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.
