Features & Applications

The SC4530WLTRT is a micropower hysteretic current-mode step-down switching regulator capable of providing up to 300 mA of output current from 3 V to 30 V input voltage range. It is designed to provide very high standby efficiency while simplifying design.

Features:

  • Input Voltage Range: 3 V to 30 V
  • Low Quiescent Current: Drawing 19mA from VIN when Stepping Down from 12 V to 3.3 V at No Load
  • High Efficiency from 12 V Input to 5 V Output
    • > 80% at 650 mA
    • > 85% at 10 mA - 300 mA
  • Up to 300 mA Continuous DC Output Current
  • Integrated Power Switch and Schottky Diodes
  • Low Output Ripple
  • < 1mA Shutdown Current
  • Hysteretic Current-Mode Control
  • Cycle-by-Cycle Current Limiting
  • Alternating Between Micropower Idling and Switching States at Light Loads to Conserve Power
  • Output Short-Circuit Protection
  • Solution Footprint as Small as 50 mm2
  • Low-Profile 3 mm x 2 mm MLPD 8-Lead Package

Applications:

  • Portable Equipment
  • Notebook Computers
  • Distributed Supplies
  • Backup Power Supplies
