  • The NCP3012 is a PWM device designed to operate from a wide input range and is capable of producing an output voltage as low as 0.8V. The NCP3012 provides integrated gate drivers and an internally set 75kHz oscillator that has the capability to synchronous to an external frequency. The NCP3012 has an externally compensated transconductance error amplifier with an internally fixed soft start. The NCP3012 incorporates output voltage monitoring with a Power Good pin to indicate that the system is in regulation. The dual function SYNC pin synchronizes the device to a higher frequency (Slave Mode) or outputs a 180 degrees out of phase clock signal to drive another NCP3012 (Master Mode). Protection features include lossless current limit and short circuit protection, output overvoltage and undervoltage protection, and input undervoltage lockout. The NCP3012 is available in a 14-pin TSSOP package. Ideal for noise sensitive applications which require minimal interference from the power supply. (Medical, Networking, etc.)
