Overview
AX2003/A 3A, 0.
25V Feedback Voltage Step-Down Switching Regulators for LED Driver ™ GENERAL DESCRIPTION AX2003/A consists of step-down switching regulator with PWM control.
These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.
AX2003/A provides low-ripple power, high efficiency, and excellent transient characteristics.
The PWM control circuit is able to the duty ratio linearly from 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 out...
