XR77103ELBTR-G1R2 MaxLinear

XR77103-G1R2 3-Output PMIC for MaxLinear G.hn Solutions Data Sheet Description FEATURES (1) The XR77103-G1R2 universal PMIC features three 2A capable , 4.5V to 14V wide input supply voltage high-efficiency synchronous buck regulators with integrated power range Built-in MOSFET and synchronous rectifier switches. They can operate in 5V, 9V and 12V powered systems with High accuracy 0.8V reference (1%) minimal required external components, thus providing the smallest Current-mode control with simple size solution possible. compensation circuit The output voltages are pre-programmed to 1.1V, 1.5V, and 3.3V. External synchronization With a nominal switching frequency of 1.14MHz, the regulators can Power good Protection also be synchronized to an external clock in applications where EMI Thermal shutdown control is critical. Overvoltage transient protection XR77103-G1R2 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, outputs are reported in regulation, and the reset timer expires. APPLICATIONS The polarity of the signal is active high. MaxLinear G.hn 1. Subject to OCP setting.
