AX3122 5A Synchronous buck Converter  GENERAL DESCRIPTION AX3122 consists of step-down switching regulator with synchronous PWM converter. These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and external NMOS etc. AX3122 provides 5A high current, 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%. An over current protect function and short circuit protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced. Also, an external compensation is easily to system stable.
