AX3121 Datasheet | AXElite

3.5A Synchronous buck Converter  GENERAL DESCRIPTION AX3121 consists of step-down switching regulator with synchronous PWM converter. These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and NMOS etc. AX3121 provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM control circuit is able to the duty ratio linearly form 0 up to 100%. This converter also contains an error amplifier circuit as well as an enable/soft-start circuit that prevents overshoot at startup. An enable function, an over current protect function and short circuit protect function are built inside, and when OCP or SCP happens, the...
