Tps54231dr soic-8 DC-DC power chip strong shipment
describe
Tps54231 device is a V and a asynchronous step-down converter, which integrates a low RDS (on) high side MOSFET. To improve efficiency under light load, skip eco mode ™ The function is activated automatically. In addition, 1 μ A shutdown supply current allows the device to be used in battery powered applications.
It simplifies the calculation of the output current with external compensation elements, and allows the calculation of the internal compensation element to be reduced. The resistance divider programs the hysteresis of input undervoltage locking. Overvoltage transient protection circuit limits voltage overshoot under startup and transient conditions.
In case of overload, cycle by cycle current limiting scheme, frequency reversal and thermal shutdown can protect the equipment and load. Tps54231 device adopts 8-pin SOIC package, which is internally optimized to improve thermal performance.
