TPS563240 - Texas Instruments

TPS563240 3-A 1.4-MHz Synchronous Step-Down Voltage Regulator

The TPS563240 is a simple, easy-to-use, 3-A synchronous step-down regulator in SOT-23 package. The peak transient output current can be 3.5 A. The devices are optimized to operate with minimum external component counts and also optimized to achieve low standby current. This switching regulator employs D-CAP3 mode control providing a fast transient response a.
