DESCRIPTION
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.
