3A, 18V, 500KHz,
Synchronous Step Down DC/DC Converter
EC3293A
General Description
The EC3293A is a high-frequency, synchronous, rectified, step-down, switch-mode converter with
internal power MOSFETs. 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.
The EC3293A has synchronous-mode operation for higher efficiency over the output current-load range.
Current-mode operation provides fast transient response and eases loop stabilization. Protection features
include over-current protection and thermal shutdown.
The EC3293A requires a minimal number of readily available, standard external components and is
available in a space-saving TSOT23-6L package.
