Texas Instruments TLV62568A/TLV62569A Step-Down Buck Converters
Texas Instruments TLV62568A/TLV62569A Step-Down Buck Converters are synchronous step-down buck DC-DC converters optimized for high efficiency and compact solution size. The device integrates switches capable of delivering an output current up to 2A. At the whole load range, the device operates in pulse width modulation (PWM) mode with 1.5MHz switching frequency. In shutdown, the current consumption is reduced to less than 2µA. An internal soft start circuit limits the inrush current during startup. Other features like overcurrent protection, thermal shutdown protection and power good are built-in.
