Frequently Asked Questions
What is the switching frequency of the UC2825AN?
The UC2825AN supports a maximum switching frequency of 1000 kHz (1 MHz), making it suitable for compact power supply designs where high frequency reduces the size of passive components such as inductors and capacitors.
What input voltage range does the UC2825AN support?
The UC2825AN operates over an input voltage range of 8.8V (minimum) to 22V (maximum), with a nominal operating voltage of 12V, allowing it to integrate easily into standard 12V power rail designs common in industrial and telecom applications.
What control mode does the UC2825AN use?
The UC2825AN uses a configurable current/voltage-mode control technique based on pulse width modulation (PWM). This dual-mode flexibility allows designers to optimize loop stability and transient response for various converter topologies including boost, buck, and flyback designs.
What package type is the UC2825AN available in?
The UC2825AN is packaged in a 16-Pin PDIP (Dual-In-Line Package), which is through-hole mounted and compatible with standard breadboard and PCB prototyping. This package is well-suited for industrial environments requiring robust mechanical connections.
Can I use the UC2825AN as a replacement for other PWM controllers?
The UC2825AN is pin and function compatible with similar current-mode PWM controllers in the UC2825 family. When evaluating alternatives, verify matching input voltage range (8.8–22V), output drive current (2A per output), switching frequency (up to 1 MHz), and package type (16-Pin PDIP) to ensure a valid drop-in replacement.
