Switch-mode Power Supplies -

Capable of either increasing or decreasing voltage.

The SMPS is omnipresent in modern technology, used in everything from smartphone chargers and laptop power bricks to industrial machinery and household appliances. While the initial manufacturing cost can be higher due to specialized components like high-frequency transformers, the long-term energy savings and reduced size make them the preferred choice for most original equipment manufacturers (OEMs).

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 Capable of either increasing or decreasing voltage

Steps up the input voltage to a higher output level. Designing Switch Mode Power Supplies With the TL598

Typically power MOSFETs or BJTs that perform the rapid switching.

Energy is stored in reactive components like inductors and capacitors during the "on" cycle and released to the load during the "off" cycle.

A "chopper" (switching transistor) converts the DC voltage into a high-frequency pulse train.
