ONSEMI UC2842BDR2G 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 capable of directly driving power MOSFETs. These ICs 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, they offer cost-effective, minimal external component solutions for efficient power regulation.
