The TPS65258RHAT is a power management integrated circuit featuring three synchronous step-down buck converters. It operates with an input voltage range of 4.5V to 16V and provides adjustable output voltages down to 0.8V with a maximum output current of 3A for Buck1 and 2A for Buck2 and Buck3. The device supports a switching frequency adjustable from 300 kHz to 2.2 MHz, set by an external resistor, and includes features such as automatic low power pulse skipping mode for improved efficiency during light loads, and forced PWM mode for consistent performance. The TPS65258RHAT incorporates built-in protection mechanisms, including overvoltage protection, thermal shutdown, and current limiting, ensuring reliable operation under various conditions. It also includes external enable pins for sequencing, soft-start capabilities, and a power good supervisor to monitor output voltages. The device is housed in a compact 40-pin QFN package, suitable for surface mount applications, and operates within a junction temperature range of -40¬8C to 125¬8C. This product is suitable for applications requiring efficient power management with multiple output voltages.
