Description
The UC3842BD is a high-performance fixed-frequency current mode controller, designed for Off-Line and DC-DC converter applications. It offers a cost-effective solution with minimal external components. This integrated circuit features a trimmed oscillator for precise duty cycle control, a temperature-compensated reference, a high-gain error amplifier, a current sensing comparator, and a high-current totem pole output, ideal for driving a power MOSFET. The UC3842BD also includes protective features such as input and reference undervoltage lockouts, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering. It is available in an 8-pin dual-in-line and surface mount (SOIC-8) plastic package, as well as a 14-pin plastic surface mount (SOIC-14) package with separate power and ground pins for the totem pole output stage. The UCX842B has UVLO thresholds of 16V (on) and 10V (off), while the UCX843B is tailored for lower voltage applications with UVLO thresholds of 8.5V (on) and 7.6V (off).Specifications and Features
