MP5496GR-0001-P

MP5496 is a complete power management solution that integrates four high-efficiency, stepdown DC/DC converters, five low-dropout (LDO) regulators and a flexible logic interface. A DC/DC converter with constant-on-time (COT) control provides fast transient response. The default 1.5MHz fixed switching frequency during continuous conduction mode (CCM) greatly reduces the external inductor and capacitor values. Full protection features include undervoltage lockout (UVLO), overcurrent protection (OCP) and thermal shutdown. The output voltage is adjustable through the I2C interface or can be preset by the one-time programmable (OTP) function. Additional features, such as AUTOON, frequency, power-on delay, RST delay, pushbutton time, LDORTC output voltage, OTP version and the I2C address can only be configured via the OTP. The MP5496 requires a minimal number of external components, and is available in a space-saving QFN-28 (4mmx4mm) package.
