The UCC3829 is a BiCMOS High Speed PWM Controller IC. It is optimized for high frequency switched mode power supply applications. The IC can be used in both voltage mode and current mode control applications. Care was given to minimizing the propagation delays through the comparators and logic circuitry while maximizing the bandwidth and slew rate of the error amplifier. The oscillator frequency and deadtime can be programmed via two external resistors and a capacitor. The undervoltage lockout threshold can be programmed using an external resistor divider. The current limit and overcurrent threshold can be set externally. The IC is available in push-pull (-1), single ended (-2), or complementary (-3) output configuration.
