AX3304  PWM Control Controller

性能描述：

        The AX3304/Aintegrates 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.

特点：

• Input voltage：8V to 40V

• Duty ratio：0% to 100% PWM control

• Oscillation frequency：100K/300KHz

• Thermal Shutdown function.

• Short Circuit Protect(SCP).

• External SW P-channel MOS.

• External OVP setting function.

• Current mode non-synchronous PWM converter

• External current limit setting.

• Under voltage Lockout.

• SOP-8L Pb-Free package.
