The ANX6701 is a high perfomance step-up converter that operates at a fixed switching frequency of 640kHz or 1.2MHz. 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 1.6A and can support output voltages up to 24V.
To minimize the inrush current a built-in soft start circuit sets the soft start period to 3.4ms. This period can be extended by connecting an optional capacitor to the SS pin. Loop response can be adjusted by external RC compensation. The ANX6701 is available in a thin MSOP-8 green package.
