DESCRIPTION

The MPM3593 is a high-frequency,

synchronous, rectified, step-down module with

an I

2C 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

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 I

2C serial interface. The

voltage slew rate, switching frequency (fSW),

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

components. 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.
