MPQ3452DL-AEC1-LF-P

MPQ3452 is a current control mode, step-up converter with a 3.5A, 90mohm internal MOSFET that provides fast transient response. It operates with an input voltage as low as 3.1V and can generate up to 22V. The MPQ3452 features a configurable switching frequency of up to 2MHz for easy filtering and low noise. An external compensation pin allows the user to flexibly set loop dynamics and operates with small, low ESR ceramic output capacitors. The soft start feature provides a small inrush current and can be programmed with an external capacitor. Full protection features include undervoltage lockout (UVLO), current limiting and thermal shutdown. The MPQ3452 is available in a low-profile QFN14 (3mmx4mm) package with an exposed pad. Applications include telecom and power supplies, microphones and tuner bias, automotive systems.
