Description
The KA7500C is used for the control circuit of the pulse-
width modulation switching regulator. The KA7500C
consists of 5V reference voltage circuit, two error
amplifiers, flip flop, an output control circuit, a PWM
comparator, a dead-time comparator, and an oscillator.
This device can be operated in the switching frequency
of 1kHz to 300kHz. The precision of voltage reference
(V
provides a better output voltage regulation. The
operating temperature range is -25°C ~ +85°C.
REF
