Overview
TK75001 PWM CONTROLLER FEATURES s s s s s s s s Optimized for Off-Line Operation Maximum Duty Ratio 44% (typ.
) Maximum Clock Frequency Above 1 MHz Frequency Reduction for Improved Overcurrent Protection Low Standby Current for Current-Fed Start-Up Current-Mode or Voltage-Mode Control Internal User-Adjustable Slope Compensation Functionally Integrated & Simplified 5-pin Design APPLICATIONS s s s s Off-Line Power Supplies Industrial Power Supplies Telecom Power Supplies Off-Line Battery Chargers DESCRIPTION The TK75001 is a simplified primary side controller optimized for off-line switching power supplies.
It is suitable for both voltage-mode and current-mode control and has advanced features not available in controllers with a higher pin count.
The key to full functionality in a 5-pin design is that the current signal and the error signal are added together and fed into the feedback pin.
A sawtooth current flowing out of the feedback pin provides a slope compensation ramp (in current-...
