The UCC38C45 is a BiCMOS low-power current mode PWM 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, featuring rise and fall times of 25ns and 20ns, respectively. The UCC38C45 is specified for operation in the temperature range of 0°C to 85°C and is available in an 8-pin VSSOP package, which helps minimize board space. It is compatible with the UCx84x family of PWM controllers, providing an enhanced replacement option. The device also incorporates undervoltage lockout protection and a ±1% accurate 2.5V error amplifier reference, making it suitable for switch-mode power supplies and general-purpose DC-DC converters.
