* Current mode operation:500 kHz * Low start-up current value<0.5mA * Latching PWM for cycle-by-cycle current limiting * Trimmed oscillator discharge current * Automatic.

The UTC UC2843B provides off-line or DC-DC fixed-frequency current-mode control design with minimum external components. Internally-implemented circuits include an under-voltage lockout (UVLO) and a precision reference with accuracy at the error ampl.
