Frequently Asked Questions

What is the input voltage range of the UC2845ANG4?

The UC2845ANG4 operates over an input voltage range of 8.2V to 28V, with a nominal supply voltage of 15V. The undervoltage lockout (UVLO) threshold ensures the controller starts up only when supply voltage is sufficient, protecting the system from erratic operation during power-on.

What switching frequency does the UC2845ANG4 support?

The UC2845ANG4 supports switching frequencies up to 500 kHz, set by an external RC timing network connected to the oscillator pin. Higher frequencies allow for smaller magnetic and capacitive components, reducing overall power supply size and cost in the final design.

What are typical applications for the UC2845ANG4?

Typical applications include flyback and forward DC-DC converters, off-line switch-mode power supplies, battery chargers, and industrial power modules. The current-mode control technique provides inherent cycle-by-cycle overcurrent protection, making it suitable for demanding telecom and industrial environments.

Is the UC2845ANG4 RoHS compliant?

Yes, the UC2845ANG4 is RoHS compliant (Pbfree Code: Yes, JESD-609 Code: e4), indicating it is manufactured without restricted hazardous substances. This makes it suitable for use in environmentally regulated markets in Europe, Asia, and North America.
