升压 (Boost) 变换器

SY7080 is a 1.2MHz fixed frequency, Current mode, high efficiency synchronous boost regulator that converts down to 0.9V input into up to 4V output voltage. It adopts very low Rdson N-MOS for the main switch and P-MOS for the synchronous switch, so no external Schottky didode is required, and the sy • 0.9V to 4V wide input range\r\n• 4V max output voltage\r\n• 1.8A internal switch\r\n• Up to 95% efficiency\r\n• < 1uA shut down current\r\n• 1.2MHz switching frequency\r\n• Minimum on time: 80ns typical\r\n• Minimum off time: 60ns typical\r\n• Output disconnect at shutdown\r\n• Low RDS(ON) (ma;
