Information

The LXDC2HL series is a low power step-down DC-DC converter suitable for space-limited or noise-sensitiveapplications. The device utilizes an inductor-embedded ferrite substrate that reduces radiated EMI noise andconduction noise.By adding input/output capacitors, it can be used as an LDO replacement. Its low noise and easy-to-assemblefeatures assure reliable power supply quality.The device works in PFM mode at light load for extended battery life. At heavy load, it changes to PMW modeautomatically and maintains high efficiency using synchronous rectifying technology.The device provides good output voltage accuracy even in PFM mode. It maintains 2% DC voltage accuracy overthe full current range (0-600mA), and shows very smooth mode transition between PFM mode and PWM mode.

Key Features

  • Low EMI noise and small footprint (5mm2 ) using inductor-embedded ferrite substrate
  • High efficiency using synchronous rectifier technology at 3MHz operation
  • PFM/PWM automatic mode switching function
  • Smooth mode transient between PFM mode and PWM mode with low-ripple-voltage PFM mode
  • 2% DC voltage accuracy over full load current range
  • Wide input voltage range : 2.3~5.5V
  • Maximum Load Current: 600mA (depends on output voltage)
  • Internal soft start, overcurrent protection
  • Better reliability at high temperature operation compared to typeA
  • 1.35V output voltage
