Package Style:  DFN-6D
Mounting Method: Surface Mount
Features & Applications

The ST1S09PUR is a step-down DC-DC converter with synchronous rectification, optimized for powering low output voltage applications.

The device is thermally protected and the output current limited to prevent damages due to accidental short circuit. A high PWM switching frequency (1.5 MHz) allows the use of tiny surface-mount components.

Features:

  • 1.5 MHz fixed frequency PWM with current control mode
  • 2 A output current capability
  • Typical efficiency: > 90%
  • 2 % DC output voltage tolerance
  • Two versions available: power good or inhibit
  • Integrated output over-voltage protection
  • Non switching quiescent current: (typ) 1.5 mA over temperature range
  • RDSON (typ) 100 mΩ
  • Utilizes tiny capacitors and inductors
  • Operating junction temp. -30 °C to 125 °C
  • Available in DFN6 (3 x 3 mm) exposed pad
