NCL30100: LED Driver Controller, Fixed, Off Time, Switch Mode

The NCL30100 is a compact switching regulator controller intended for space constrained constant current high brightness LED driver applications where high efficiency and small size are important. The controller is based on a peak current, quasi fixed off time control architecture optimized for continuous conduction mode stepdown (buck) operation. This allows the output filter capacitor to be eliminated. In this configuration, a reverse buck topology is used to control a cost effective N-channel MOSFET.

Features
  • Quasi-Fixed Off Time, Peak Current Control Method
  • Reverse Buck Switching Topology
  • Up to 700 kHz Switching Frequency
  • Up to 95%+ Efficiency
  • No Output Capacitor Needed
  • Vcc Operation from 6.35-18 V
  • -40 to 125 °C
Benefits
  • No Loop Compensation Needed
  • N-FET MOSFETs can be used
  • Allows smaller inductors
