XR77103

Universal PMIC

3-Output Programmable Buck Regulator

Description

FEATURES

4.5V to 14V wide input supply voltage

The XR77103 features three synchronous wide input range high

efficiency buck converters. Each converter is digitally programmable

requiring minimal external components thus providing the smallest

size solution possible.

ꢀ■

range

ꢀ■

Built-In MOSFET and synchronous rectifier

I²C programmable supplies

Output voltage (0.8 to 6V)

Power on sequence

The converters can operate in 5V, 9V, and 12V systems and have

integrated power switches. The output voltage of each converter

Soft-start timing

can be adjusted by programming the values in the V

setting

Switching frequency (300kHz to

2.2MHz)

Individual current limit

Optional power saving mode at light

loads

Non volatile memory (NVM) with up to

10,000 times write operation

0.8V, high accuracy reference (1%)

Current-mode control with simple

compensation circuit

External synchronization

registers through I²C interface. The adjustable range is 0.8 to 6V with

50mV resolution. The output voltage also can be set externally using

an external resistor divider. Output sequence among the outputs,

soft-start time and the peak inductor current limit are also set

through I²C.

ꢀ■

The switching frequency of the converters can either be set with I²C

or can be synchronized to an external clock connected to SYNC pin

if needed. The switching regulators are designed to operate from

300kHz to 2.2MHz. Each converter operates in phase or out-of-phase

according to the value in the phase setting register. This can minimize

the input filter requirements.

ꢀ■

Thermal shutdown

Overvoltage transient protection

Overcurrent protection

32-pin 4mm x 4mm TQFN package

XR77103 features

supervisor circuit that monitors each

converter output. PGOOD pin is asserted once sequencing is 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

Video processor supplies

Applications processor power

ꢀ■

XR77103 also features a light load pulse skipping mode (PSM). It is

set through I²C. The PSM mode allows for a reduction on the input

power supplied to the system when the host processor is in stand-by

(low activity) mode.
