With a 2.9V to 4.8V input-voltage range, the STMP30 PMIC contains three integrated DC-DC converters to provide all the

power rails needed for AMOLED displays in smartphones and other portable devices. The voltage can be set between 4.6V

and 5.0V to optimize the display brightness for lowest power consumption and best visibility under any conditions. The 5.0V

maximum setting allows high-brightness mode (HBM) for best viewing in bright outdoor lighting.

The remaining two programmable voltages (-0.8V to -6.6V, and 5.5V to 7.9V) are programmed using single-wire (S-Wire)

protocol through external pins. The PMIC also receives S-Wire messages to operate the AMOLED in always-on display (AOD)

mode, which improves user convenience by showing information on-screen continuously at very low power.

The PMIC has a true shutdown mode that helps maximize power savings, as well as safety features such as thermal

protection, input undervoltage lockout, and soft-start with inrush current limiting. In addition, the high- voltage outputs feature

fast-discharge circuitry and short-circuit protection.
