Frequently Asked Questions
What control modes does the UC3823N support?
The UC3823N supports both current-mode and voltage-mode PWM control. In current-mode operation, the peak switch current is sensed and used directly in the feedback loop, providing inherent current limiting and faster transient response. In voltage-mode operation, the output voltage error signal alone controls the duty cycle, simplifying current sensing requirements.
What is the maximum switching frequency of the UC3823N?
The UC3823N can operate at switching frequencies up to 1000 kHz (1 MHz). This high switching frequency enables the use of smaller inductors and capacitors in the power stage, reducing the overall size and cost of the converter while maintaining good regulation performance and transient response.
What is the gate drive output current capability of the UC3823N?
The UC3823N provides a peak gate drive output current of 1.5A. This high drive capability allows direct switching of medium to large power MOSFETs at high frequencies without requiring an external gate driver buffer, reducing component count and improving switching transition times in the power stage.
What package does the UC3823N use and what is its input voltage range?
The UC3823N is housed in a 16-pin plastic dual in-line package (PDIP), identified by JESD-30 code R-PDIP-T16, suitable for through-hole PCB assembly and prototyping. Its input voltage range is 10V minimum to 12V maximum, with a nominal supply voltage of 15V, compatible with standard 12V and 15V power rails used in industrial and computing power supply designs.
