UC3526AN Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the UC3526AN is 12V to 35V, with a maximum voltage rating of 40V.
  • To ensure stable operation, ensure that the input voltage is within the recommended range, decouple the power supply with a 10uF capacitor, and use a minimum of 100nF capacitor on the Vref pin.
  • The Vref pin is used to set the internal reference voltage, which is used to regulate the output voltage. It should be connected to a 10kΩ resistor to ground and a 100nF capacitor to filter out noise.
  • Yes, the UC3526AN can be used as a voltage regulator, but it is primarily designed as a pulse-width modulation (PWM) controller for switching power supplies. It can be used to regulate the output voltage, but it may not provide the same level of regulation as a dedicated voltage regulator IC.
  • The frequency of the UC3526AN can be calculated using the formula: f = 1 / (RT * CT), where RT is the resistance of the timing resistor and CT is the capacitance of the timing capacitor.
