Conv DC-DC 3.5V to 28V Step Down Single-Out 0.8V to 25V 2A 8Pin SOIC Tube
Description
The TPS54231 device is a 2-V, 2-A non-synchronous buck converter that integrates a low RDSon 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
