Overview
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.
