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.
