The TLV62568A, TLV62569A devices 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 2 A. At the whole load range, the device operates in pulse width modulation (PWM) mode with 1.5-MHz switching frequency. In shutdown, the current consumption is reduced to less than 2 µA.
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 device is available in a SOT563 package.
