MPM3593 Datasheet | Monolithic Power Systems

DESCRIPTION The MPM3593 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 (VIN) range. The MPM3593 integrates an internal high-side MOSFET (HS-FET) and low-side MOSFET (LSFET) to achieve high efficiency without requiring an external Schottky diode. With internal pensation and a feedback divider, the device provides a very pact solution that requires a minimal number of readily available, standard external ponents. 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 (f SW), enable, and power-save mode are also configurable via the I2C interface. This allows the user to optimize each output for different specifications. During bench evaluations, different configurations can be easily obtained via the I2C interface instead of reworking external ponents. Once the desired optimal configuration is achieved, a multi-page OTP memory can permanently store the settings. Current mode operation provides fast transient response and eases loop stabilization. Full protection features include under-voltage lockout (UVLO), over-voltage protection (OVP), over-current protection (OCP), and overtemperature protection. The MPM3593 is available in a QFN-41 (6mmx8mm) package.
