CA1523
Voltage Regulator Control Circuit
for Variable Switching Regulator
Description
The CA1523 monolithic silicon integrated circuit is a variable
interval pulse regulator designed to provide the control cir-
cuitry for use in switching regulator circuits. It operates from
11V to 15V.
The regulator provides a single output drive capable of
300mA source/200mA sink. The maximum operating fre-
quency is better than 200kHz. An attractive feature of the
CA1523 is that the timing capacitor charge and discharge
current is set up externally via a single resistor. The ratio of
charge to discharge current is internally set at a maximum of
2 to 1 allowing simultaneous change in output pulse width
with increased frequency at higher load. The pulse width
variation at higher frequencies effectively compensates for
the losses in magnetics and thereby increases the power
supply efficiency at higher load end by as much as 20
percent.
Features
• Operates up to 200kHz
• Pins ESD Protected
• Remote ON/OFF
• Slow Start with Reset
• Overcurrent Sensing
• Lower Peak Currents than PWM Regulator
- Less Prone to Magnetic Saturation
