DESCRIPTION

The UTC UC3842G of high performance current mode

controller is specifically designed for off-line and DC-to-DC

converter applications offering the designer a cost effective

solution with minimal external components. This integrated

circuit features approximately 300μA start up current,

precision reference trimmed the error amplifier input. Also

included are protective features consisting of input and

reference undervoltage lockouts each with hysteresis,

cycle-by-cycle current limiting, and so on.
