Manufacturer	Microsemi
File Size	666.70 KB
Description	Current Mode PWM Controller
Datasheet	SG1843-MicrosemiCorporation.pdf
Note	This datasheet PDF includes multiple part numbers: SG1842, SG1843. 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-bypulse 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-u.
