VOLTAGE-MODE PWM CONTROLLERThe KA3525A is a monolithic integrated circuit that Included all of
the control circuit necessary for a pulse width modulating regulator.
There are a voltage reference, an error amplifier, a pulse width
modulator, an oscillator, under-voltage lockout, soft start circuit, and
output drivers in the chip.
FEATURES 5V 1% Reference Oscillator Sync Terminal Internal Soft Start Deadtime Control Under-Voltage Lockout
