The UCC28084DR is a BiCMOS pulse width modulation (PWM) controller designed for DC-DC or off-line fixed-frequency current-mode switching power supplies. It features a dual output stage configured for push-pull topology, with a maximum duty cycle of 49%. The device operates within a supply voltage range of 4.1 V to 15 V and has a typical switching frequency of 200 kHz. Key features include programmable slope compensation, internal soft-start with a typical interval of 3.5 ms, and cycle-by-cycle current limiting. The UCC28084DR also incorporates an undervoltage lockout with hysteresis, ensuring reliable operation. It is available in an 8-pin SOIC package and is suitable for applications such as high-efficiency switch-mode power supplies and telecom DC-DC converters. The operating temperature range is from -40¬8C to 85¬8C, making it versatile for various environments. Engineers considering this product should note its capability for synchronous rectification and its configuration for low-cost push-pull and half-bridge applications.
