Product Overview
Product Description
The NCP1579 is a low cost PWM controllers designed to operate from a 5V or 12V supply. These devices are capable of producing an output voltage as low as 0.8V. These 8 pin devices provide an optimal level of integration to reduce size and cost of the power supply. The NCP1579 provides a 1A gate driver design and an internally set 275kHz oscillator. Other efficiency enhancing features of the gate driver include adaptive non overlap circuitry. The NCP1579 also incorporates an externally compensated error amplifier and a capacitor programmable soft start function. Protection features include programmable short circuit protection and under voltage lockout.
