Texas Instruments UCC3808-2 Low Power Current Mode Push-Pull PWM UCC3808D-2

The UCC3808-2 is a low power current mode push-pull PWM controller designed for high-speed applications. It features dual output drive stages in a push-pull configuration, allowing for efficient operation up to 1 MHz. The device has a typical starting current of 130 OºA and a run current of 1 mA, making it suitable for power-sensitive applications. It includes an internal soft-start mechanism and an on-chip error amplifier with a gain bandwidth of 2 MHz, which aids in maintaining output voltage regulation. The UCC3808-2 is capable of driving output stages with a peak source current of 500 mA and a peak sink current of 1 A. It is particularly well-suited for use in server and desktop power supplies, telecom power supplies, DC-DC converters, and switched-mode power supplies. The device operates with an undervoltage lockout threshold of 4.3 V for turn-on and 4.1 V for turn-off, providing additional safety in power management applications. The UCC3808-2 is packaged in an 8-pin SOIC format, making it compact for integration into various designs.
