XR77103-A0R5

Universal PMIC 3-Output Buck Regulator

Description

FEATURES

4.5V to 14V wide input supply

The XR77103-A0R5 universal PMIC features three 2A synchronous

high-efficiency, buck regulators with integrated power switches. They

can operate in 5V, 9V and 12V powered systems with minimal required

external component thus providing the smallest size solution possible.

Two of the outputs may be paralleled for output currents up to 5A peak

with steady state current of up to 4A.

Protection

The output voltage of each converter can be adjusted by external

resistordividerdowntovoltageaslowas0.8V.Withanominalswitching

frequency of 500kHz, the regulators can also be synchronized to an

external clock in applications where EMI control is critical.

Thermal shutdown

Overvoltage transient protection

Overcurrent protection

32-pin 4mm x 4mm TQFN package

XR77103-A0R5 features a supervisor circuit that monitors each

converter output. PGOOD pin is asserted once sequencing is done,

outputs are reported in regulation and the reset timer expires.

The polarity of the signal is active high. A pulse skipping mode (PSM)

reduces switching losses maintaining high efficiency when the system

is unloaded or in standby mode.
