说明

• Typical Application for SC1403 Mobile Multi-Output PWM Controller with Lossless Current Sense. The SC1403 is a multiple-output power supply controller designed to power battery operated systems. The SC1403 provides synchronous buck converter control for two (3.3V and 5V) power supplies. An efficiency of 95% can be achieved for the two supplies. The SC1403 uses proprietary Virtual Current Sense technology along with external error amplifier compensation to achieve enhanced stability and DC accuracy over a wide range of output filter components while maintaining fixed frequency operation
