NCP1587E Low Voltage Synchronous Buck Controller The NCP1587E 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 NCP1587E 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 device also incorporates an externally compensated error amplifier and a capacitor programmable soft−start function.
Protection features include programm...
