KA3525A Regulating Pulse Width Modulator IC DIP-16
The KA3525A is a monolithic integrated circuit that incorporates all the essential control circuits for a pulse-width modulating (PWM) regulator. This versatile IC integrates a voltage reference, an error amplifier, a pulse width modulator, an oscillator, an under-voltage lockout circuit, a soft-start feature, and the output driver all on a single chip. It is specifically designed to drive N-channel power MOSFETs and is a staple in switch-mode power supplies and other power control circuits. The KA3525A generates two complementary PWM signals, enabling precise control over the output voltage through a feedback mechanism that compares the output signal to a stable reference voltage.
