DESCRIPTION

The TPS6265x device is a high-frequency

synchronous step-down dc-dc converter optimized for

battery-powered portable applications. Intended for

low-power applications, the TPS6265x supports up to

800mA 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

I2C interface down to 0.75V, the device supports

low-voltage DSPs and processors core power

supplies in smart-phones and handheld computers.

The TPS6265x operates at a regulated 6MHz

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 3.5μA.

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 12.5mV,

for setting the output voltage or reprogramming the

mode of operation (PFM/PWM or Forced PWM) for

instance.

The TPS6265x is available in an 9-pin chip-scale

package (CSP).
