NCP1589A, NCP1589B
Low Voltage Synchronous
Buck Controller
The NCP1589A/B 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 device is capable of converting
voltage from as low as 2.5 V. This 10 ? pin device provides an optimal
level of integration to reduce size and cost of the power supply.
Features include a 1.5 A gate driver design and an internally set
300 kHz or 600 kHz oscillator. In addition to the 1.5 A gate drive

capability, other efficiency enhancing features of the gate driver
include adaptive non ? overlap circuitry. The NCP1589A/B also
incorporates an externally compensated error amplifier. Protection
features include programmable short circuit protection and
