ONSEMI UC2842BD1R2G Current Mode Controller
The UC2842B series are high-performance fixed frequency current mode controllers designed for off-line and DC-DC converter applications. They feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, and a high current totem pole output suited for driving power MOSFETs. Protective features include undervoltage lockout with hysteresis, cycle-by-cycle current limiting, programmable deadtime, and a latch for single pulse metering. Available in SOIC-8 and SOIC-14 packages, these devices offer a cost-effective, reliable solution with minimal external components, ideal for modern power supply designs.
