NCP3020: Synchronous PWM Controller

Description: The NCP3020 is a Synchronous Buck Controller (PWM ...
  • The NCP3020 is a Synchronous Buck Controller (PWM Controller) designed to operate from a wide input range and is capable of producing an output voltage as low as 0.6 V. The NCP3020A provides integrated gate drivers and an internally set 300 kHz oscillator (600 kHz for the NCP3020B).

    The NCP3020 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.
  • Features
  • Input voltage from 4.7 V to 28 V - Ability to regulate from different input voltage sources
  • 0.6 V +/-1.5% Reference Voltage - Capable of low output voltage operation
  • 300 kHz Operation (NCP3020B - 600 kHz) - Optimize for efficiency or size
  • >1A Drive Capability - Ability to drive low Rdson high efficiency MOSFETs
  • Current Limit and Short Circuit Protection - Advanced protection features
  • Output Overvoltage and Undervoltage Detection - Advanced protection features
  • Transconductance Amplifier with External Compensation - Ability to utilize all ceramic input and output capacitors
  • Integrated boost diode - Reduced number of support components and cost
  • Regulated Soft-start - Closed loop regulation during soft-start prevents any spikes or droops
  • AEC-Q100 and PPAP compliant (NCV3020) - Ideal for automotive applications
