UC3843BVD1R2G Description

Short technical summary and product information.

The ON Semiconductor UC3843BVD1R2G is a fixed-frequency current mode controller designed for efficient Off-Line and DC-DC converter applications. It offers a cost-effective solution with minimal external components, featuring a trimmed oscillator for precise duty cycle control and a temperature-compensated reference.

 

Key electrical specifications include an operating voltage range of 7.6V to 30V, a maximum duty cycle of 96%, and a switching frequency up to 500kHz. The device also includes features such as undervoltage lockout with hysteresis, cycle-by-cycle current limiting, and a high current totem pole output.

 

This controller is housed in an 8-SOIC surface mount package. It operates within a temperature range of -40°C to 105°C. The UC3843BVD1R2G is suitable for applications requiring precise control over power conversion.

 

Environmental compliance includes RoHS3 compliance and Halide-Free status. The part is supplied in a Reel package with a standard quantity of 2500 units.
