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).
