NCP3020A, NCP3020B

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.
