XR77103 Universal PMIC 3-Output Programmable Buck Regulator Description FEATURES The XR77103 features three high efficiency, wide input range, 4.5V to 14V wide input supply voltage synchronous buck converters. Each converter is digitally range Built-In MOSFET and synchronous rectifier programmable requiring minimal external components, thus providing 2 I C programmable supplies the smallest size solution possible. Output voltage (0.8V to 6V) The converters can operate in 5V, 9V, and 12V systems and have Power on sequence integrated power switches. The output voltage of each converter can Soft-start timing be adjusted by programming the values in the V setting registers Switching frequency (440kHz to OUT 2 2.3MHz) through the I C interface. The adjustable range is 0.8V to 6V with Individual current limit 50mV resolution. The output voltage also can be set externally using Optional power saving mode at light an external resistor divider. The output sequence among the outputs, loads soft-start time, and the peak inductor current limit are also set Non volatile memory (NVM) with up to 2 through I C. 10,000 times write operation 2 High accuracy 0.8V reference (1%) The switching frequency of the converters can either be set with I C Current-mode control with simple or can be synchronized to an external clock connected to SYNC pin compensation circuit if needed. The switching regulators are designed to operate from External synchronization 440kHz to 2.3MHz. Each converter operates in phase or out-of-phase Power good according to the value in the phase setting register. This can minimize Protection the input filter requirements. Thermal shutdown Overvoltage transient protection XR77103 features a supervisor circuit that monitors each Overcurrent protection converter output. The PGOOD pin is asserted once sequencing is 32-pin 4mm x 4mm TQFN package done, all outputs are reported in regulation, and the reset timer expires. The polarity of the signal is active high. APPLICATIONS FPGA and DSP supplies XR77103 also features a light load pulse skipping mode (PSM). It is 2 Video processor supplies set through I C. The PSM mode allows for a reduction on the input Applications processor power power supplied to the system when the host processor is in stand-by (low activity) mode.
