Datasheet Summary
Low Voltage Synchronous Buck Controller
The NCP81046 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 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 externally pensated error amplifier. Protection...
