... which gives a soft-start time of approximately 2.5ms. To adjust the soft-start time, determine the C7 using the following formula: C7 = (8µA x tSS)/0.6V where tSS is the required soft-start time in seconds and C7 is in farads. C7 should be a minimum of 1nF capacitor between REFIN/SS and GND. When no ...

Surface-mount technology



Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD). In the industry it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. Both technologies can be used on the same board for components not suited to surface mounting such as large transformers and heat-sinked power semiconductors.An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or no leads at all. It may have short pins or leads of various styles, flat contacts, a matrix of solder balls (BGAs), or terminations on the body of the component.
