UC3844BVD1R2G Description

Short technical summary and product information.

The UC3844BVD1R2G from ON Semiconductor is a fixed-frequency current mode controller designed for off-line and DC-DC converter applications. It offers a cost-effective solution with minimal external components.

 

Key electrical specifications include an operating voltage range of 10V to 36V, a maximum duty cycle of 48%, and a switching frequency of up to 500kHz. The device also features a 1000mA output current capability and a typical output voltage range of 4.9V to 5.1V.

 

This controller is housed in an 8-SOIC package and is designed for surface mounting. It operates within a temperature range of -40°C to 105°C. The UC3844BVD1R2G integrates features such as an oscillator, a temperature-compensated reference, a high-gain error amplifier, and a high-current totem pole output.

 

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