产品信息

 
GENERAL DESCRIPTION
    AX3112 consists of step-down switching regulator with PWM control. The device
includes a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.
    AX3112 provides low-ripple power, high efficiency, and excellent transient
characteristics. The PWM control circuit is able to the duty ratio linearly forms 0 up to 100%. An enable function, an over current protect function and short circuit protect function are built outside that it can set by a resistance. An internal compensation block is built in to minimum external component count.
    With the addition of an internal P-channel Power MOS, a coil, capacitors, and a diode connected externally, these ICs can function as step-down switching regulators. They serve as ideal power supply units for portable devices when coupled with the SOP-8L-EP package, providing such outstanding features as low current consumption. Since this converter can accommodate an input voltage up to 38V, it is also suitable for the operation via an AC adapter.
