Beschreibung

The ETA3499 is a high-efficiency, DC-DC step-down switching regulator, capable of delivering up to 3A output current. The devices operate from an input voltage range of 2.4V to 7.3V and provide output voltage from 0.6V to VIN, making ETA3499 ideal for low voltage power conversions. Running at a fixed frequency of 1MHz allows the use of small inductance value and low DCR inductors, thereby achieving higher efficiency. Other external components, such as ceramic input and output caps can also be small due to higher switching frequency, while maintaining exceptional low noise output voltage. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improved design reliability.

Eigenschaften

  • Wide Input Voltage Range: 2.4 – 7.3V
  • Standby Current 42uA (Vout=1.2V, Iout=0A)
  • Up to 96% Efficiency
  • Up to 3A Max Output Current
  • 1MHz Frequency
  • Light Load operation
  • Internal Compensation
  • Tiny SOT23-6L Package

Typische Anwendungen

  • Set-Top-Box / IP camera / Telecom Devices
