Synchronous PWM Controller
Description
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.
