3 Description

The TPS562242 is a simple, easy-to-use, high

efficiency, high power density, synchronous buck

converter with input voltage ranging from 3-V to 16-V

and supports up to 2-A continuous current at output

voltages between 0.8 V and 7 V.

The TPS562242 employs D-CAP3 control mode to

provide a fast transient response and to support

low-ESR output capacitors with no requirement for

external compensation. The device can support up to

93 duty cycle operation.

The TPS562242 operates in Eco-mode, which

maintains high efficiency during light loading. The

device integrates complete protection through OVP,

OCP, UVLO, OTP, and UVP with hiccup.

The device is available in 1.6-mm × 1.6-mm SOT-563

package. The junction temperature is specified from

–40°C to 125°C.
