NCP81046: Single Phase Buck Controller
The NCP81046 is a low cost PWM controller designed to operate from a 5V or 12V 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 2.5V. 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 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 NCP81046 also incorporates an externallycompensated error amplifier. Protection features include programmable short circuit protection and undervoltage lockout(UVLO).
