产品描述:
Step-Down Regulator 2A, 28V Input, 570kHz Step Down SWIFT DC-DC Converter with Eco-Mode Conv DC-DC 3.5V to 28V Step Down Single-Out 0.8V to 25V 2A 8Pin SOIC T/R
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.

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
