The NCP1587 and NCP1587A are 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 NCP1587 and NCP1587A provide a 1A gate driver design and an internally set 275kHz (NCP1587) and 200kHz (NCP1587A) oscillator. Other efficiency enhancing
