NiQor Series

Buck-boost HV Non-Isolated DC/DC Converters

The high input voltage NiQor family of DC-DC converters offers unique solutions for converting high‑powered, variable voltages to a wide range of output voltages. The converter is a non-isolated buck‑boost regulator, which employs synchronous rectification to achieve extremely high conversion efficiency. These products are suitable for use in IBA, or to provide a regulated output voltage from a variable voltage source such as a battery. They can be configured to ‘buck’ the input voltage down or ‘boost’ the input voltage up using a single external resistor.

Operational Features

  • Ultra-high efficiency up to 96%
  • Wide input voltage ranges: 9-20V (NQ20); 9-40V (NQ40); 9-60V (NQ60); 9-90V (NQ90)
  • Buck or Buck/Boost Mode available
  • Maximum input/output currents up to 55A
  • Suitable for use in Intermediate Bus Architectures
  • On-board input and output filtering
  • No minimum load requirement
  • Remote sense and wide output voltage trim

Battery Charging

NiQor Non-Isolated DC-DC Converters for Battery Charging Applications

  • Provides the power conversion platform for battery charging
  • Output current limit is externally controlled for constant‑current charging
  • Current can be set with an external resistor or an active circuit
  • Current analog signal provided for instrumentation and control functions
  • Ideal diode output stage with zero back-drive currents prevents discharge of battery when not charging
  • Output voltage set-point is independently controlled through trim pin
  • Unit will smoothly transition between current and voltage modes as charging cycle needs charge

Protection/Control Features

  • Input under-voltage lockout (UVLO)
  • Output current limit (OCP) and short circuit protection
  • Output over-voltage protection (OVP)
  • Thermal shutdown (OTP)
  • Output voltage trim
