产品概述
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.
