Frequently Asked Questions
What is the operating voltage range of the UC3853N?
The UC3853N operates with an input voltage range of 11.2 V minimum to 40 V maximum, with a nominal operating voltage of 16 V. This wide range makes it suitable for universal AC input power factor correction designs.
What switching frequency does the UC3853N use?
The UC3853N operates at a switching frequency of 82.5 kHz. This relatively high frequency allows designers to use smaller inductors and capacitors in power factor correction boost converter stages, reducing overall solution size.
What control method does the UC3853N implement?
The UC3853N uses current-mode pulse width modulation (PWM) control. This technique provides inherent cycle-by-cycle current limiting, faster transient response, and improved stability compared to voltage-mode control in power factor correction applications.
What package does the UC3853N come in and what are its pin count?
The UC3853N is available in an 8-pin PDIP (Plastic Dual In-Line Package) through-hole package. This form factor simplifies prototyping and is compatible with standard 0.3-inch DIP sockets commonly found in evaluation boards.
Is the UC3853N RoHS compliant?
Yes, the UC3853N is Pb-free (lead-free) and carries a Pb-free code of Yes with JESD-609 code e4, confirming it meets RoHS environmental compliance requirements for use in modern electronic systems.
