NCP1588 Datasheet, PDF (1/10 Pages) ON Semiconductor – Low Voltage Synchronous Buck Controller

NCP1588
Low Voltage Synchronous
Buck Controller
The NCP1588 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. The
NCP1588 provides 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 NCP1588 also incorporates an externally
compensated error amplifier. Protection features include
programmable short circuit protection and undervoltage lockout
(UVLO).
