AX3050/A is a wide input voltage, high efficiency Active CC step down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. AX3050/A consists of step down switching regulator with PWM control. The devi c e includes a reference voltage source, oscillation circuit, error amplifier and etc. AX3050/A provides low ripple power, high efficiency, and excellent transient characteri stics. The PWM control circuit is able to the duty ratio linearly forms 0 up to 90%. An over current protection function is built outside that it can set by a resistance. An external compensation is easily to system stable; the low ESR output capacitor can be used.
They serve as ideal power supply units for portable devices when coupled with th e SOP 8L EP package s , providing such outstanding features as low current consumption. Since this converter can acco mmodate an input voltage up to 36
