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

300ꢀkHz 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).
