MP5470

4V-16V, Power Management IC with Four 3A/3A/2A/2A Buck Converters and Flexible System Setting via I²C and MTP

Datasheet EN

Description

The MP5470 is a complete power management IC that integrates four high-efficiency, step-down, DC/DC converters and a flexible logic interface.

Constant-on-time (COT) control provides fast transient response. The programmable switching frequency (up to 1.6MHz) reduces the external inductor and capacitor size greatly. Full protection features include under-voltage lockout (UVLO), over-current protection (OCP), over-voltage protection (OVP), and thermal warning/shutdown.

The output voltage is adjustable through the I²C bus or can be preset by the three-time programmable multi-time programmable (MTP) e-Fuse. The power on/off sequence is also programmable by the MTP.

The MP5470 requires a minimal number of external components and is available in a space-saving QFN-22 (3mmx4mm) package.
