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.
Features
• Input Voltage Range from 4.7 V to 28 V
• 1.2 MHz Operation (NCP3030B – 2.4 MHz)
• 0.8 V Internal Reference Voltage
• Internally Programmed 1.8 ms Soft−Start (NCP3030B – 1.3 ms)
• Current Limit and Short Circuit Protection
• Transconductance Amplifier with External Compensation
• Input Undervoltage Lockout
• Output Overvoltage and Undervoltage Detection
• NCV Prefix for Automotive and Other Applications Requiring Site
and Change Controls
• These are Pb−Free Devices
