Operating at 3MHz switching frequency with 95% peak efficiency, it requires only three tiny external components (inductor, input cap, output cap). The internal synchronous rectifier eliminates the Schottky diode, reducing component count. 18uA quiescent current and power-save mode extend battery life in portable applications.","working_principle":"The ADP2108 uses a current-mode PWM control scheme at 3MHz fixed frequency. The high-side PMOS switch and low-side NMOS synchronous rectifier alternate to step down the input voltage. Under light load, power-save mode reduces the effective switching frequency to maintain efficiency. 100% duty cycle mode allows the output to follow the input when VIN approaches VOUT. Internal compensation and soft start simplify design.","pin_description":"
