NCV3030A

NCP3030A, NCP3030B, NCV3030A, NCV3030B Synchronous PWM Controller The NCP3030 is a PWM device designed to operate from a wide input range and is capable of producing an output voltage as low as 0.6 V. The NCP3030 provides integrated gate drivers and an internally set 1.2 MHz (NCP3030A) or 2.4 MHz (NCP3030B) oscillator. The NCP3030 also has an externally compensated transconductance error amplifier with an internally fixed soft−start. Protection features include lossless current limit and short circuit protection, output overvoltage protection, output undervoltage protection, and input undervoltage lockout. The NCP3030 is currently available in a SOIC−8 package.
