The NCP158x 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

300kHz 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).
