Texas Instruments  TLV62568PDRLR

The TLV62568 device is a synchronous step-down buck DC-DC converter optimized for highefficiency and compact solution size. The device integrates switches capable of delivering anoutput current up to 1 A.

At medium to heavy loads, the device operates in pulse width modulation (PWM) mode with1.5-MHz switching frequency. At light load, the device automatically enters Power Save Mode (PSM)to maintain high efficiency over the entire load current range. In shutdown, the currentconsumption is reduced to less than 2 µA.

The TLV62568 provides an adjustable output voltage via an external resistor divider. Aninternal soft start circuit limits the inrush current during startup. Other features like overcurrent protection, thermal shutdown protection and power good are built-in. The device isavailable in a SOT23 and SOT563 package.
