  <title>[elecena] AST1S31HF Up to 4 V, 3 A step-down 2.3 MHz switching regulator for automotive applications - zmiany ceny</title>
  <description>The AST1S31HF is an internally compensated 2.3 MHz fixed frequency PWM synchronous step-down regulator. The AST1S31HF operates from 2.8 V to 4 V input, while it regulates an output voltage as low as 0.8 V and up to VIN.

The AST1S31HF device integrates a 70 mΩ high-side switch and a 55 mΩ synchronous rectifier allowing very high efficiency with very low output voltages.

The peak current mode control with internal compensation deliver a very compact solution with a minimum component count.

The AST1S31HF is available in a 3 mm x 3 mm, 8-lead VFDFPN package.</description>
