Switch-mode Power Supplies Site

Output voltage is maintained through Pulse Width Modulation (PWM) , where the duty cycle (ratio of on-to-off time) is adjusted by a feedback mechanism to compensate for load or input variations. 3. Common Topologies

Steps up the input voltage to a higher output level. Switch-Mode Power Supplies

Often a PWM controller like the TI TL598 that manages the switching cycles. Output voltage is maintained through Pulse Width Modulation
