The UCC28C42 is a BiCMOS low current PWM current mode controller designed for high-performance applications. It operates at a maximum frequency of 1MHz and features a low startup current of 50OºA, with a maximum operating current of 100OºA. The device has a low operating current of 2.3mA at 52kHz, making it suitable for energy-efficient designs. It includes fast cycle-by-cycle overcurrent limiting with a response time of 35ns and can drive external MOSFETs with a peak output current of ¬±1A, characterized by a 25ns rise time and a 20ns fall time. The UCC28C42 is specified for operation over a temperature range of -40¬8C to 125¬8C and is compatible with the UCx84x and UCx84xA families, providing pin-to-pin compatibility. It is available in an 8-pin VSSOP package, which helps minimize board space. This controller is ideal for applications such as switch-mode power supplies and general-purpose DC-DC converters.
