The TPS62A0569x family of devices are synchronous step-down buck DC/DC converters optimized for high efficiency and compact design size. The devices integrate switches capable of delivering an output current up to 2A. At medium to heavy loads, the devices operate in peak current mode pulse width modulation (PWM) with approximately 2.4MHz 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 minimized for increased application shelf life. The TPS62A0569A variant of this device family operates in forced PWM across the whole load current range.

The TPS62A0569 devices provide an adjustable output voltage through an external resistor divider. An internal soft-start circuit limits the inrush current during start-up. Essential features like overcurrent protection, thermal shutdown protection, and power good (optional) are built-in. The devices are available in SOT563 package.
