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.
