AX3304/A

PWM Control Controller



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.


