CYPM1111-40LQXI Infineon PMIC | 40-QFN (6x6) | 4A Buck, I2C

Product Overview

The CYPM1111-40LQXI is a high-performance Power Management IC (PMIC) from Infineon, designed for space-constrained applications requiring efficient power conversion. Housed in a compact 40-QFN (6x6 mm) package, this device integrates a 4A step-down (buck) converter with I2C interface for dynamic voltage scaling. It operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for battery-powered and USB-powered systems. The PMIC delivers up to 4A continuous output current with high efficiency (>95% peak) and features programmable output voltage from 0.6V to 3.3V via I2C. Protection features include over-current, over-temperature, and under-voltage lockout.
