The MP2158GQH-Z is a monolithic step-down switch mode converter with built-in internal power MOSFETs. It achieves 1A continuous output current from a 2.5V to 6V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.6V. The Constant-On-Time control scheme provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The MP2158GQH-Z is available in the small QFN8 2.0x1.5mm package and requires a minimum number of readily available standard external components. The MP2158GQH-Z is ideal for a wide range of applications including High Performance DSPs, FPGAs, PDAs, and portable instruments.
