Frequently Asked Questions
What control modes does the UC1825AJ883B support?
The UC1825AJ883B supports current-mode control as its primary operating mode and can also be configured for voltage-mode control, providing designers flexibility to implement both control topologies in switching power supply designs including forward, flyback, and push-pull converter architectures.
What is the operating temperature range of the UC1825AJ883B?
The UC1825AJ883B is rated for a military-grade temperature range of -55 to 125°C, making it suitable for defense avionics, space electronics, military vehicles, and other harsh-environment applications where commercial-grade ICs operating only to 85°C would be unreliable.
What input voltage range does the UC1825AJ883B operate at?
The UC1825AJ883B operates with input voltages from 8.8V minimum to 20V maximum, providing compatibility with common 12V and 15V power rails used in military electronics and industrial control systems while maintaining stable PWM regulation across the full input range.
What package does the UC1825AJ883B use?
The UC1825AJ883B is packaged in a 16-Pin ceramic DIP (CDIP) which provides superior hermetic sealing and thermal performance compared to plastic packages, meeting MIL-PRF-38535 or equivalent standards for military-grade components used in aerospace and defense systems.
Is the UC1825AJ883B REACH compliant?
The UC1825AJ883B is listed as Not REACH Compliant, which is common for military and high-reliability ceramic hermetic components where specific materials required for performance and reliability may not meet REACH regulations, so designers should verify end-use application restrictions before specifying this part.
