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). The NCP1586 comes

in an 8−pin SOIC package.
