SG1526B/SG2526B/SG3526B  
REGULATING PULSE WIDTH MODULATOR  
DESCRIPTION  
FEATURES  
8 to 35 volt operation  
The SG1526B is a high-performance pulse width modulator for switching  
power supplies which offers improved functional and electrical characteris-  
tics over the industry-standard SG1526. A direct pin-for-pin replacement for  
the earlier device with all its features, it incorporates the following enhance-  
ments: a bandgap reference circuit for improved regulation and drift  
characteristics, improved undervoltage lockout, lower temperature coeffi-  
cients on oscillator frequency and current-sense threshold, tighter toler-  
ance on softstart time, much faster SHUTDOWN response, improved  
double-pulse supperession logic for higher speed operation, and an im-  
proved output driver design with low shoot-through current, and faster rise  
and fall times. This versatile device can be used to implement single-ended  
or push-pull switching regulators of either polarity, both transformer-less  
and transformer-coupled. The SG1526B is specified for operation over the  
full military ambient temperature range of -55°C to 150°C. The SG2526B  
ischaracterizedfortheindustrialrangeof-25°Cto150°C, andtheSG3526B  
is designed for the commercial range of 0°C to 125°C.
