The UC3846N from Texas Instruments is a versatile current mode PWM controller designed for fixed-frequency control schemes. It supports multiple topologies including Boost, Flyback, Forward Converter, Half-Bridge, and Push-Pull configurations.
Key electrical features include a wide input voltage range of 6.95V to 40V, an operating frequency of 500kHz, and a maximum duty cycle of 50%. The device incorporates essential control features such as current limit, enable, frequency control, and soft start. It also provides a ±1% band gap reference and 500mA peak totem-pole outputs.
Designed for enhanced performance, the UC3846N offers automatic feedforward compensation, programmable pulse-by-pulse current limiting, and automatic symmetry correction for push-pull converters. It also supports parallel operation for modular power systems and includes a differential current sense amplifier with a wide common-mode range. Protection features include undervoltage lockout and double-pulse suppression.
This controller is available in a 16-PDIP through-hole package, suitable for applications requiring robust power management solutions. The operating temperature range is from 0°C to 70°C.
