Описание TPS54231DR
The TPS54231DR is a non-synchronous Buck Converter 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 1µA 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 foldback and thermal shutdown protect the device and the load in the event of an overload condition.
• High efficiency at light loads with a pulse skipping Eco-mode™
• Adjustable slow-start limits inrush current
• Programmable UVLO threshold
• Overvoltage transient protection
• Cycle-by-cycle current limit, frequency fold back and thermal shutdown protection
• Supported by WEBENCH® software tool
• Integrated 80mR high-side MOSFET supports up to 2A continuous output current
• 1µA Typical shutdown quiescent current
• Green product and no Sb/Br
