AX4103
PWM Control 3.5A Step-Down Converter
GENERAL DESCRIPTION
AX4103 consists of step-down switching regulator with PWM control. These devise
include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and
etc.
AX4103 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.
FEATURES
- Input voltage4.5V to 23V
- Output voltage0.8V to VCC
- Duty ratio0% to 100% PWM control
- Oscillation frequency330KHz 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.
