The UC2847DW is a BiCMOS pulse-width modulation (PWM) switching controller designed for DC DC power conversion. It operates at a fixed frequency of 500kHz with a maximum duty cycle of 50%. The controller supports multiple topologies including boost, flyback, forward converter, full-bridge, half-bridge, and push-pull. It provides two transistor driver outputs with synchronous rectification and clock synchronization capability. Control features include current limit, enable, frequency control, and soft start. The device operates from a supply voltage range of 6.95V to 40V and is specified for an ambient temperature range of -40°C to 85°C. The UC2847DW is offered in a 16-pin SOIC surface mount package with a width of 7.50mm. This controller is suitable for a variety of power supply designs requiring high-frequency operation and flexible topology selection.
