About This Product

■Summary

The MPM4730 is a synchronous rectifier, 4-switch integrated buck-boost module with an input voltage (VIN) range of 2.8V to 22V. The device regulates the output voltage (VOUT) with high efficiency and includes VOUT scaling and output current (IOUT) limiting. The MPM4730 uses constant on-time (COT) control in buck mode and constant off-time control in boost mode for fast load transient response and smooth buck-boost mode transients.The MPM4730 features automatic pulse frequency modulation (PFM)/pulse width modulation (PWM) or forced PWM switching modes. The device features selectable switching frequency (fSW) and programmable soft-start. Extensive protection features include overcurrent protection (OCP), overvoltage protection (OVP), undervoltage protection (UVP), and thermal shutdown. The MPM4730 is available in an ECLGA-18 (3mm x 3mm) package.

■Features and benefits

・2.8V~22V operating input voltage (VIN) range ・Reference voltage (VREF) from 0.08V to 1.637V ・0.8mV resolution via I2C (default 1V VREF) ・Output voltage (VOUT) configurable via FB pin ・1A maximum output current (IOUT) ・Selectable switching frequency (fSW) of 500kHz / 750kHz ・Overvoltage protection (OVP) and short circuit protection (SCP) with hiccup mode ・Over temperature warning (OTW) and shutdown ・I2C interface and ALT pin ・One-time programmable (OTP) non-volatile memory (NVM) ・I2C configurable pulse frequency modulation (PFM) / pulse width modulation (PWM) modes, soft start (SS), overcurrent protection (OCP), and OVP ・Configurable EN shutdown discharge ・Provided in ECLGA-18 (3mm x 3mm x 1.86mm) package

■Available product numbers

・MPM4730GPQ-0000-Z MPM4730GPQ-xxxx-Z MPM4730GPQ-0000-P MPM4730GPQ-xxxx-P ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
