TPS54239EDDAR +BOM

Compact and reliable step-down conversion solution

TPS54239EDDAR General Description

One of the key advantages of the TPS54239E is its adaptive on-time control, which allows for seamless transition between PWM mode at higher load conditions and Eco-mode™ operation at lighter loads. This ensures high efficiency across a wide range of operating conditions, making it ideal for applications where power consumption varies

Key Features

  • Wide input voltage range of 4.5V to 28V
  • 2A output current capability
  • Efficiency up to 95%
  • Integrated 110mΩ high side MOSFET
  • Adjustable switching frequency up to 1MHz
  • Built-in overcurrent and thermal shutdown protection
  • Power good indicator for output voltage monitoring
  • Application

  • The TPS54239EDDAR is commonly used in various applications such as point-of-load regulation, distributed power systems, industrial equipment, telecommunications, and consumer electronics where efficient power conversion is required
  • It is specifically designed for step-down (buck) voltage regulation in a wide range of input voltage applications
