GENERAL DESCRIPTION
L4003 consists of step-down switching
regulator with PWM control.
These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.
L4003 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%.
This converter is build out soft start function that prevents overshoot and inrush current at startup.
