Description
TPS54231DR 2-A 28-V Input Step-Down DC-DC Converter With Eco-mode™
The TPS54231DR is a 2-A, 28-V input step-down DC-DC converter featuring Eco-mode™ technology for enhanced efficiency at light loads. This non-synchronous buck converter integrates a low RDS(on) high-side MOSFET and is designed for battery-powered applications with minimal shutdown current.
Key Features
  • 3.5- to 28-V input voltage range
  • Adjustable output voltage down to 0.8 V
  • Integrated 80-mΩ high-side MOSFET supports up to 2 A continuous output current
  • High efficiency at light loads with pulse skipping Eco-mode™
  • Fixed 570-kHz switching frequency
  • Typical 1-μA shutdown quiescent current
  • Adjustable slow-start limits inrush currents
  • Programmable UVLO threshold
  • Overvoltage transient protection
  • Cycle-by-cycle current limit, frequency fold back and thermal shutdown protection
  • Available in easy-to-use SOIC8 package
Product Description
The TPS54231 device is a 2-V, 2-A non-synchronous buck converter that integrates a low RDS(on) high-side MOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode™ feature is automatically activated. Furthermore, the 1-μA shutdown supply current allows the device to be used in battery powered applications. Current mode control with internal slope compensation simplifies the external compensation calculations and reduces component count while allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis of the input undervoltage lockout. An overvoltage transient protection circuit limits voltage overshoots during startup and transient conditions. A cycle-by-cycle current limit scheme, frequency fold back and thermal shutdown protect the device and the load in the event of an overload condition. The TPS54231 device is available in an 8-pin SOIC package that has been internally optimized to improve thermal performance.
