NCV3020A

NCP3020A, NCP3020B, NCV3020A, NCV3020B Synchronous PWM Controller The NCP3020 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 NCP3020 provides integrated gate drivers and an internally set 300 kHz (NCP3020A) or 600 kHz (NCP3020B) oscillator. The NCP3020 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 NCP3020 is currently available in a SOIC−8 package.
