Description
The UC2842ADR2 is a high-performance fixed frequency current mode controller designed for off-line and DC-to-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. It also includes protective features such as undervoltage lockouts, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering. The UC2842ADR2 is available in an 8-pin dual-in-line plastic package and a 14-pin plastic surface mount package with separate power and ground pins for the totem pole output stage.Specifications and features
