Texas Instruments TPS562242 | Demoboard TPS562242EVM

Description

The TPS562242 is a single, adaptive on-time, D-CAP3™ control mode, synchronous buck converter that requires a very low external component count. The D-CAP3 control mode is optimized for low-ESR output capacitors such as POSCAP, SP-CAP, or ceramic types, and features fast transient response with no external compensation. The switching frequency is internally set at a nominal 1.4 MHz and enters Eco-mode in light load conditions. The high-side and low-side switching MOSFETs are incorporated inside the TPS562242 packagealong with the gate-drive circuitry. The TPS562242 DC/DC synchronous converter is designed to support up to a 2-A continuous current from an input voltage source of 3 V to 17 V. The output voltage range is from 0.8 V to 10 V. Rated input voltage and output current ranges for the evaluation module are given in Table 1-1.
