ENERAL DESCRIPTION
The AX3304 integrates Pulse-Width-Modulation (PWM) control circuit into a single
chip, mainly designs for power-supply regulator. All the functions include an error amplifier,a soft-start, UVLO, OVP, SCP, TSD circuitry.
This device features an internal 100KHz oscillator (300KHz for "A" version), the
UVLO makes sure that the outputs are off until the internal circuit operates normally.
