The EC6705 is a high perfomance step-up converter that operates at a fixed switching frequency
The high switching frequency allows the use of small inductors and fast transient response.
The integrated N-channel FET has a typical current limit of 1.4A and can support output voltages up
to 22V. The feedback voltage is 1.23V.
To minimize the inrush current a built-in soft start circuit is contained. To minimize the external component count EC6705 also provides the internal compensation.
The loop response is optimized for fast transient panel loading. The EC6705 is available in a thin TSOT23-5 green package.
