» Product Change Notification
The NCP10970 is an auxiliary power solution which optimized for micro controller unit or DSP based system. It is included a high-voltage switcher for 9~16 VOUT, a linear regulator for 3.3 / 5.0 VOUT and over-temperature/ over-current protection on 16SOP. NCP1097x provide the best class standby power.
Features   Benefits
     
  • Highly Integrated multiple blocks - 670V Input Buck Switcher - 3.3 V/100 mA LDO (A1 option) - 5.0 V/100 mA LDO (B1 option)
 
  • Small form factor design
  • Dual Output Buck
 
  • Low LDO power loss
  • Standby mode by MCU
 
  • Low no load input power
  • Protections/Utility functions - Fault In/Out Pin – fast response comparator - Demagnetization detection - Short-circuit Protection on Buck,LDO - Internal thermal shutdown
 
  • High system reliability - Flexible design (OTP/OCP) - Stable operation w/o CCM - Easy to pass safety certification
  • Patented VRAW generation for LDO Input
 
  • Achieve Good Standby Power performance
