EV5470-L-00A

12V Power Management IC Evaluation Board

Datasheet

Description

The EV5470-L-00A is an evaluation board for MP5470, a complete power management solution which integrates four high efficiency step-down DC/DC converters and flexible logic interface.

COT control DC/DC converter provides fast transient response. Up to 1.6MHz programmable switching frequency greatly reduces external inductor and capacitor size.

Full protection features include UVLO, OCP and thermal shut down.

Output voltage is adjustable through I2C bus or preset by 3 times programmable MTP (Multi Time Programmable) eFuse. The power on/off sequence is also programmable by MTP.

The MP5470 requires a minimal number external components, and is available in space saving 22-pin QFN (3x4mm) package.
