EV5496-R-00A

EV5496-R-00A is an evaluation board for MP5496, a complete power management solution that integrates four high-efficiency, step-down, DC/DC converters, five low-dropout regulators, and a flexible logic interface. A constant-on-time (COT) control DC/DC converter provides fast transient response. The 1.5MHz default fixed switching frequency during continuous conduction mode (CCM) reduces external inductor and capacitor values greatly. Full protection features include undervoltage lockout (UVLO), over-current protection (OCP), and thermal shutdown. Output voltage is adjustable through the I2C bus or pre-set by the one-time programmable (OTP) function. The power on/off sequence is also programmable by the OTP or can be controlled through I2C bus online. The MP5496 requires a minimal number of external components and is available in a space-saving, 28-pin QFN (4mmx4mm) package. Applications include cable modems, set-top boxes, televisions, MID, tablets, POS machines, SSD and IP cameras.
