NCP1586 Low Voltage Synchronous Buck Controller The NCP1586 is a low cost PWM controller designed to operate from a 5 V or 12 V supply. This device is capable of producing an output voltage as low as 0.8 V. This 8−pin device provides an optimal level of integration to reduce size and cost of the power supply. The NCP1586 provides a 1 A gate driver design and an internally set 275 kHz oscillator. In addition to the 1 A gate drive capability, other efficiency enhancing features of the gate driver include adaptive non−overlap circuitry. The NCP1586 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 (UVLO).
