LM2524D/LM3524D  
Regulating Pulse Width Modulator  
pulse per period even in noisy environments. The LM3524D  
includes double pulse suppression logic that insures when a  
shut-down condition is removed the state of the T-flip-flop will  
change only after the first clock pulse has arrived. This feature  
prevents the same output from being pulsed twice in a row,  
thus reducing the possibility of core saturation in push-pull  
designs.  
General Description  
The LM3524D family is an improved version of the industry  
standard LM3524. It has improved specifications and addi-  
tional features yet is pin for pin compatible with existing 3524  
families. New features reduce the need for additional external  
circuitry often required in the original version.  
The LM3524D has a ±1% precision 5V reference. The current  
carrying capability of the output drive transistors has been  
raised to 200 mA while reducing VCEsat and increasing VCE  
breakdown to 60V. The common mode voltage range of the  
error-amp has been raised to 5.5V to eliminate the need for  
a resistive divider from the 5V reference.  
Features  
Fully interchangeable with standard LM3524 family

±1% precision 5V reference with thermal shut-down  
Output current to 200 mA DC  
In the LM3524D the circuit bias line has been isolated from  
the shut-down pin. This prevents the oscillator pulse ampli-  
tude and frequency from being disturbed by shut-down. Also  
at high frequencies (≃300 kHz) the max. duty cycle per output  
has been improved to 44% compared to 35% max. duty cycle  
in other 3524s.  
60V output capability  
Wide common mode input range for error-amp  
One pulse per period (noise suppression)  
Improved max. duty cycle at high frequencies  
Double pulse suppression  
Synchronize through pin 3  
In addition, the LM3524D can now be synchronized external-  
ly, through pin 3. Also a latch has been added to insure one
