The switching frequency of 5MHz enables the use of extremely small filter components, resulting in smaller board space and reduced BOM costs. When the input current is greater than approximately 50mA, the TS33001/2/3 utilizes PWM voltage mode feedback with input voltage feed-forward to provide a wide input voltage...
