The SG1842/43 family of control ICs provides all the necessary features to implement off-line fixed frequency, current-mode switching power supplies with a minimum number of external components. Current-mode architecture demonstrates improved line regulation, improved load regulation, pulse-by-pulse current limiting and inherent protection of the power supply output switch.
The bandgap reference is trimmed to ±1% over temperature. Oscillator discharge current is trimmed to less than ±10%.
The SG1842/43 has under voltage lockout, current limiting circuitry and start-up current of less than 1mA.KEY
