Description

    The TK75005 is an 8-pin PWM controller suitable for both voltage-mode and current-mode control. It also has advanced features not available in controllers with a higher pin count. One such feature is a sawtooth current flowing out of the feedback pin (FB), which provides a slope compensation ramp (in current mode applications) in proportion to the resistance terminating that FB pin.

    The TK75005 offers the same features as the TK75003 with the addition of the Error Amplifier and the Overvoltage Protection (OVP) functions, and the deletion of the Overcurrent Frequency Reduction feature.

    This PWM has features similar to the UC3842 (please refer to UC3842 Comparison Section).
