TPS563231 - Texas Instruments

TPS563231 3-A Synchronous Step-Down Voltage Regulator

The TPS563231 is a simple, easy-to-use, 3-A synchronous step-down converter in SOT563 package. The device is optimized to operate with minimum external component counts and also optimized to achieve low standby current. These switch mode power supply (SMPS) devices employ D-CAP3 mode control providing a fast transient response and supporting both lowequivale.
