 GENERAL DESCRIPTION

The AX3304/A 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.
