3 Description

The TPS62864 and TPS62866 devices are high-

frequency synchronous step-down converters with I²C

interface which provide an efficient, adaptive, and

high power-density solution. At medium to heavy

loads, the converter operates in PWM mode and

automatically enters Power Save Mode operation at

light load to maintain high efficiency over the entire

load current range. The device can also be forced in

PWM mode operation for smallest output voltage

ripple. Together with its DCS-control architecture,

excellent load transient performance and tight output

voltage accuracy are achieved. Via the I²C interface

and a dedicated VID pin, the output voltage is quickly

adjusted to adapt the power consumption of the load

to the ever-changing performance needs of the

application.

Selection by external resistor

– Start-up output voltage

– I²C slave address

•

Selection by I²C interface

– Power save mode or forced PWM mode

– Output discharge

– Hiccup or latching short-circuit protection

– Output voltage ramp speed

VID pin for dynamic voltage scaling (DVS)

Thermal pre-warning and thermal shutdown

Power good indicator pin option

I²C-compatible interface up to 3.4 Mbps

Available in 1.05-mm x 1.78-mm x 0.5-mm 15-pin

WCSP package with 0.35-mm pitch
