Voltage Adjustment: Replacing the fixed resistor on Pin 1 with a 10k or 20k potentiometer allows for a variable output (typically 3V to 24V).Current Limiting: Using the second error amplifier (Pins 15 and 16) connected to a shunt resistor allows you to set a maximum current, preventing short-circuit fires. Safety Warnings Safety Warnings By adding dead-time control (Pin 4),
By adding dead-time control (Pin 4), proper frequency compensation (Type 2 network), and dedicated gate drivers, you transform a basic 50% duty cycle oscillator into a robust, high-efficiency converter.
