MP5424GRM-0000-P

MP5424 is a complete power management solution that integrates four high-efficiency stepdown DC/DC converters, three low-dropout (LDO) regulators, one load switch, and a flexible logic interface. Constant-on-time (COT) control in the DC/DC converter provides fast transient response. The 1.1MHz default switching frequency (fSW) during continuous conduction mode (CCM) greatly reduces the external inductance and capacitance. Full protection features include undervoltage lockout (UVLO) protection, overcurrent protection (OCP), overvoltage protection (OVP) and thermal shutdown. The output voltage (VOUT) can be adjusted via the I2C bus or preset by the multiple-time programmable (MTP) interface. The start-up/shutdown sequence can also be configured via the MTP and controlled via the I2C bus. Applications include general consumer, camera modules, 3.3V/5V powered systems and space-limited systems.

• Four 4.5A/2.5A/4.5A/2A buck converters, three 300mA low-noise LDO
• Buck 1 and buck 3 can work in parallel, buck 2 and buck 4 can work in parallel
• 2.7V to 5.5V operating VIN range
• Adjustable switching frequency (fSW), adjustable soft-start time (tSS) and adjustable phase delay
• Configurable forced PWM (FPWM) mode or Auto-PFM/PWM mode
• 2.7V to 5.5V/3A load switch, 50mohm on-resistance at VIN = 5V
• I2C bus and user-programmable MTP, start-up/shutdown control
• Enable pin (EN1) for sleep mode entry and recovery control
• Start-up reset output, flexible start-up/shutdown sequence via MTP
• Requires a minimal number of external components, available in a small QFN-26 (3.5mmx4.5mm) package

MPS part numbers ending in "-P" and "-Z" are the same parts. P & Z only indicates reel size.
