General Description<\/h3>\n\n\n\n

The EC3293B is a high-frequency, synchronous, rectified, step-down, switch-mode converter with internal
power MOSFETs.<\/p>\n\n\n\n

It offers a very compact solution to achieve a 3A continuous output current over a wide input supply range, with excellent load and line regulation.<\/p>\n\n\n\n

The EC3293B has synchronous-mode operation for higher efficiency over the output current-load range.<\/p>\n\n\n\n

Current-mode operation provides fast transient response and eases loop stabilization.Protection features include
over-current protection and thermal shutdown.<\/p>\n\n\n\n

The EC3293B requires a minimal number of readily available, standard external components and is available in
a space-saving TSOT23-6L package.<\/p>\n\n\n\n
