Description	CURRENT MODE PWM CONTROLLER
Datasheet	SG1842-Linfinity.pdf
Note	This datasheet PDF includes multiple part numbers: SG1843, SG1842. Please refer to the document for exact specifications by model.

The SG1842/43 family of control IC's provides all the necessary

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 undervoltage lockout, current limiting circuitry and start-u.
