ASTEC AS2208
The AS2208 is a simplified pulse width modulation controller, offering similar functionality as that of the AS3842. The PWM function is controlled by the current sense comparator for normal current mode control. The COMP pin, which serves as an input to the current sense comparator, provides a 1 mA current source which can be tied directly to the control loop optocoupler.| Part No. | AS2208 |

DESCRIPTION
Based on the AS2214, the AS2208 provides the additional features of low startup current and overvoltage latching, making it a good solution for adapter applications. The output stage is a high current totem pole output that sees only 85 ns delay from the PWM comparator. The AS22
