Description
The S-8353A45MC-IRET2G is a step-up, super-small package, 1.2 MHz PWM / PFM switchable switching regulator. It is a CMOS step-up switching regulator that consists of a reference voltage source, an oscillation circuit, an error amplifier, a phase compensation circuit, a current limit circuit, and a start-up circuit. The S-8353A45MC-IRET2G is designed to prevent a decrease in efficiency caused by the IC's operating current by skipping pulses under light load operation.
