CA1524, CA2524  
CA3524  
Regulating Pulse Width Modulator  
October 2000  
Features  
Description  
• Complete PWM Power Control Circuitry  
The CA1524 and CA3524 are silicon monolithic integrated  
circuits designed to provide all the control circuitry for use in  
a broad range of switching regulator circuits.  
• Separate Outputs for Single-Ended or Push-Pull  
Operation  
The CA1524 and CA3524 have all the features of the indus-  
try types SG1524, SG2524, and SG3524, respectively. A  
block diagram of the CA1524 series is shown in Figure 1.  
The circuit includes a zener voltage reference, transconduc-  
tance error amplifier, precision R-C oscillator, pulse-width  
modulator, pulse-steering flip-flop, dual alternating output  
switches, and current-limiting and shutdown circuitry. This  
device can be used for switching regulators of either polarity,  
transformer-coupled dc-dc converter, transformerless volt-  
age doublers, dc-ac power inverters, highly efficient variable  
power supplies, and polarity converter, as well as other  
power-control applications.  
• Line and Load Regulation. . . . . . . . . . . . . . . 0.2%(Typ)  
• Internal Reference Supply with 1% (Max) Oscillator  
and Reference Voltage Variation Over Full  
Temperature Range  
• Standby Current of Less Than 10mA  
• Frequency of Operation Beyond 100kHz  
• Variable-Output Dead Time of 0.5µs to 5µs  
• Low VCE(sat) Over the Temperature Range  
Applications  
Ordering Information  
• Positive and Negative Regulated Supplies  
• Dual-Output Regulators
