DESCRIPTION  
KEY FEATURES  
■ OPTIMIZED FOR OFF-LINE CONTROL  
■ LOW START-UP CURRENT (<1mA)  
■ AUTOMATIC FEED FORWARD  
COMPENSATION  
■ TRIMMED OSCILLATOR DISCHARGE  
The SG1842/43 family of control IC's  
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.  
voltage lockout, current limiting  
circuitry and start-up current of less  
than 1mA.  
The totem-pole output is optimized  
to drive the gate of a power MOSFET.  
The output is low in the off state to  
provide direct interface to an N  
channel device.  
The SG1842/43 is specified for  
operation over the full military ambient  
temperature range of -55°C to 125°C.  
The SG2842/43 is specified for the  
industrial range of -25°C to 85°C, and  
the SG3842/43 is designed for the  
commercial range of ꢁ°C to 7ꢁ°C.  
CURRENT  
■ PULSE-BY-PULSE CURRENT LIMITING  
■ ENHANCED LOAD RESPONSE  
CHARACTERISTICS  
■ UNDER-VOLTAGE LOCKOUT WITH 6V  
HYSTERESIS (SG1842 only)  
■ DOUBLE-PULSE SUPPRESSION  
■ HIGH-CURRENT TOTEM-POLE OUTPUT  
The bandgap reference is trimmed to  
1ꢀ over temperature. Oscillator  
discharge current is trimmed to less  
than 1ꢁꢀ. The SG1842/43 has under-
