This datasheet also covers the NCP1588 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.
General Description
Pin No.
Supply rail for the floating top gate driver.
input voltage to this pin (cathode connected to BOOT pin).
Key Features
include a 1.5 A gate driver design and an internally set 300ĂkHz 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 NCP158x also incorporates an externally compensated error amplifier. Protection features include programmable short circuit protection and undervoltage lockout (UVLO). Features.

signed 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 300ĂkHz 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 NCP158x also incorporates an externally compensated error amplifier. Protection features include programmable
