Download the NCP1589B datasheet PDF.
This datasheet also covers the NCP1589A variant, as both devices belong to the same low voltage synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.
Key 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 undervoltage lockout (UVLO). Features.

er 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.
