Tps54331dr soic-8 switching regulator Ti sold at the lowest price
The tps54331 device is a 28V, 3-asynchronous pressure converter that integrates a low RDS (on) high side MOSFET. In order to improve the efficiency under light load, the pulse jump ecological mode function will be activated automatically. In addition, 1- μ A shutdown power supply current allows the device to be used for battery powered applications.
Current mode control with internal slope compensation simplifies external compensation calculations, reduces component counts, and allows the use of ceramic output capacitors. A resistance divider is programmed to lock the hysteresis of the input low voltage. The overvoltage transient protection circuit limits the voltage over-frequency under startup and transient conditions. Cycle by cycle current limiting scheme, frequency folding and thermal shutdown can protect equipment and load in case of overload. Tps54331 equipment has 8-pin SOIC package and 8-pin sopowerpad package, which have been internally optimized to improve thermal performance.
