UC2843BD1R2 Description

Short technical summary and product information.

The UC2843BD1R2 is a DC-DC switching controller from On Semiconductor designed for boost and flyback topologies. It operates from an input voltage range of 7.6V to 30V and provides a single transistor driver output with positive, isolation-capable configuration. The controller features a maximum duty cycle of 96% and a switching frequency up to 500kHz, with frequency control capability. It is a non-synchronous rectifier design with no clock sync.

 

The device is housed in a surface-mount 8-SOIC package with a width of 3.90mm. It is rated for an operating temperature range of -25°C to 85°C. This controller is suitable for power supply designs requiring step-up or step-up/step-down regulation, including isolated flyback converters.
