Texas Instruments TPS562242 2A Synchronous Buck Converters

Texas Instruments TPS562242 2A Synchronous Buck Converters are simple, easy-to-use, high efficiency, high power density, synchronous buck converters with input voltage ranging from 3V to 17V. These devices support 2A continuous current at output voltages between 0.8V and 10V.

The Texas Instruments TPS562242 employs the D-CAP3 control mode to provide a fast transient response and support low-ESR output capacitors without external compensation. The device can support up to 94% of duty cycle operations. 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 1.6mm × 1.6mm SOT-563 package. The junction temperature is specified from –40°C to 125°C.
