TLV62568 Step-Down Buck Converters

Texas Instruments' TLV62568 are 1 A high efficiency step-down buck converters in SOT23 and SOT563 packages

Image of Texas Instruments' TLV62568 Step-Down Buck ConvertersTexas Instruments' TLV62568 devices are synchronous step-down buck DC-DC converters optimized for high efficiency and compact solution size. The devices integrate switches capable of delivering an output current up to 1 A.

At medium to heavy loads, the devices operate in pulse width modulation (PWM) mode with 1.5 MHz switching frequency. At light load, the devices automatically enter power save mode (PSM) to maintain high efficiency over the entire load current range. In shutdown, the current consumption is reduced to less than 2 µA.

The TLV62568 provides an adjustable output voltage via an external resistor divider. An internal soft start circuit limits the inrush current during startup. Other features like over current protection, thermal shutdown protection, and power good are built-in. The devices are available in SOT23 and SOT563 packages.
