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
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
