MONOLITHIC POWER SYSTEMS (MPS) MPM3593GQY-0001 DC-DC Switching Synchronous Buck Regulator, Adjustable, 3.5 to 45 V In, 0.8 to 12V/3 A Out, QFN-41

MPM3593GQY-0001-T is a high-frequency, synchronous, rectified, step-down module with an I²C control interface and a multi-page onetime programmable (OTP) memory. It can achieve up to 3A of continuous output current (IOUT), with excellent load and line regulation across a wide input voltage range. The MPM3593 integrates an internal high-side MOSFET (HS-FET) and low-side MOSFET to achieve high efficiency without requiring an external Schottky diode. With internal compensation and a feedback divider, the device provides a very compact solution that requires a minimal number of readily available, standard external components. The MPM3593 is flexibly designed to support a 0.8V to 12V output voltage (VOUT) that can be adjusted on the fly via an I²C serial interface. The voltage slew rate, switching frequency (fSW), enable, and power-save mode are also configurable via the I²C interface. Application includes industrial power systems, automotive power systems, telecommunication systems.
