TPS62650TYFFRQ1-Automotive 2.3V to 5.5V, 6MHz Fixed Frequency 800mA Buck Converter

The TPS62650-Q1 device is a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. Intended for low-power applications, the TPS62650-Q1 supports up to 800-mA load current and allows the use of small, low-cost inductors and capacitors.

The device is ideal for mobile phones and similar portable applications powered by a single-cell Li-Ion battery. With an output voltage range adjustable via an I2C interface down to 0.75 V, the device supports low-voltage core power supplies for DSPs and processors in smart-phones and handheld computers.

The TPS62650-Q1 operates at a regulated 6-MHz switching frequency and enters the efficiency-optimized power-save mode operation at light load currents to maintain high efficiency over the entire load current range. In the shutdown mode, the current consumption is reduced to less than 3.5 µA.

The serial interface is compatible with Standard, Fast/Fast Plus and High-Speed mode I2C specification allowing transfers at up to 3.4 Mbps. This communication interface is used for dynamic voltage scaling with voltage steps down to 12.5 mV for setting the output voltage or reprogramming the mode of operation (PFM/PWM or Forced PWM), for instance.
