The eSR-Tugela, a component of the DELTA library, is an inductor-based buck switching regulator with high efficiency.

Key Benefits

  • High efficiency buck regulator (up to 95% peak), over wide load current range
  • Pulse With Modulation (PWM) mode enabling to master the frequency response
  • Automatic mode change of the Power Stage Unit, maintaining high-efficiency at low load current
  • Support of 5 V input for USB or Lithium battery
