UC3845BVD1R2G Description

Short technical summary and product information.

The UC3845BVD1R2G from On Semiconductor is a fixed-frequency, current-mode controller optimized for off-line and DC-DC converter applications. This integrated circuit offers a cost-effective solution with minimal external components, featuring an oscillator, a temperature-compensated reference, a high-gain error amplifier, and a current-sensing comparator.

 

Key electrical specifications include an operating voltage range of 7.6V to 30V, a maximum duty cycle of 48%, and the capability for output switching frequencies up to 500kHz. The device supports Boost and Flyback topologies and provides essential control features like frequency control.

 

Designed for surface mounting, the UC3845BVD1R2G comes in an 8-SOIC package. Its operating temperature range is -40°C to 105°C (TA). This controller is suitable for applications requiring efficient power conversion and precise control.

 

Protective features include undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, and a latch for single-pulse metering. The output deadtime can be programmed from 50% to 70%.
