AX4102-PWM Control 3.5A Step-Down Converter


AX4102-PWM Control 3.5A Step-Down Converter DataSheet

GENERAL DESCRIPTION
    AX4102 consists of step-down switching regulator with PWM control. These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.
    AX4102 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%. An enable function, 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 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 package, providing such outstanding features as low current consumption. Since this converter can accommodate an input voltage up to 23V, it is also suitable for the operation via an AC adapter.

FEATURES
- Input voltage:3.6V to 23V
- Output voltage:0.8V to VCC
- Duty ratio:0% to 100% PWM control
- Oscillation frequency:330KHz typ.
- Current Limit (CL), Enable function.
- Thermal Shutdown function.
- Short Circuit Protect (SCP).
- Built-in internal SW P-channel MOS.
- SOP-8L Pb-Free package.
