E-CMOS EC3293
The EC3293 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 EC3293 has synchronous-mode operation for higher efficiency over the output current-load range.| Part No. | EC3293 |
