Features & Applications

The STEVAL-ISA055V1 is a synchronous step-down DC-DC converter with enable function based on the ST1S12XX. It is optimized for powering low-voltage digital cores in HDD (hard disk drive) applications and is generally used to replace high-current linear solutions when power dissipation may cause high heating of the application environment.

The ST1S12 device is thermal protected and current limited to prevent damage due to accidental short-circuit. This family of products is available in the TSOT23-5L package.

Features:

  • Step-down current mode PWM (1.7 MHz) DCDC converter
  • Fixed output voltage of 1.2 V
  • 0.7 A output current capability
  • 3% DC output voltage tolerance
  • Synchronous rectification
  • Enable function
  • Internal soft-start
  • Typical efficiency: > 90%
  • Not switching quiescent current: max 600 μA over temperature range
  • RDS(on) typ. 250 m Ω and 400 m Ω
  • Uses tiny capacitors and inductors
