The UC3842B, UC3843B, UC2842B, and UC2843B are high-performance fixed frequency current mode controllers designed for off-line and DC-DC converter applications.
These devices feature a trimmed oscillator for precise duty cycle control, temperature-compensated reference, high-gain error amplifier, current sensing comparator, and a high-current totem pole output stage.
Key Features:
Undervoltage lockout with hysteresis, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering.
Available in 8-pin dual-in-line and surface mount (SOIC-8) packages, as well as 14-pin plastic surface mount (SOIC-14) packages with separate power and ground pins for the totem pole output stage.
Applications:
Off-line and DC-DC converter applications, offering a cost-effective solution with minimal external components.
