【文字介紹】SY7068 is a high efficiency, synchronous, adaptive constant on time control, step-up converter designed for one-cell Li-Ion or Li-polymer, or two to three-cell alkaline Ni-Cd or Ni-MH battery powered applications.
It can convert down to 2.3V input voltage. It adopts NMOS for the main switch and PMOS for the synchronous switch. SY7068 is a boost regulator designed to provide a minimum output voltage from a single-cell Li-Ion battery, even when the battery voltage is below system minimum. It can support up to 2A load current. It can transition smoothly between Bypass and normal Boost Mode. It can be forced into Bypass Mode to reduce the quiescent current.
