XR77129  
40V Quad Output Digital PWM/PFM  
Universal PMIC  
FEATURES  
General Description  
Quad Channel Step-down Controller  
Digital PWM 105kHz-1.23MHz Operation  
Individual Channel Frequency Selection  
Patented digital PFM with Ultrasonic mode  
Patented Over Sampling Feedback  
Programmable 5 coefficient PID control  
Integrated MOSFET Drivers  
6V to 40V Input Voltage  
0.6V to 5.5V Output Voltage (higher with exter-  
nal feedback resistors)  
SMBus Compliant I2C Interface  
Full Power Monitoring and Reporting  
3 x 15V Capable PSIO + 2 x GPIOs  
Full Start/Stop Sequencing Support  
The XR77129 is a quad channel digital Pulse Width Modulated (PWM)  
step down (buck) controller. A wide 6V to 40V input voltage range allows  
for single supply operation from standard power rails.  
With integrated FET gate drivers, two LDOs for standby power and a  
105kHz to 1.23MHz independent channel to channel programmable con-  
stant operating frequency, the XR77129 reduces overall component  
count, solution footprint and optimizes conversion efficiencies. A select-  
able digital Pulse Frequency Mode (PFM) capable of better than 80% effi-  
ciency at light current load and low operating current allow for portable  
and Energy Star compliant applications. Each XR77129 channel’s output  
voltage is individually programmable down to 0.6V with a resolution of  
2.5mV, and is configurable for precise soft start and soft stop sequencing,  
including delay and ramp control.  
Built-in Thermal, Over-Current, UVLO and Out-  
2
The XR77129 operations are fully controlled via a SMBus-compliant I C  
put Over-Voltage Protections  
interface allowing for advanced local and/or remote reconfiguration, full  
performance monitoring and reporting as well as fault handling.  
On Board 5V and LDOOUT Standby LDOs  
On Board Non-Volatile Memory  
Built-in independent output Over-Voltage, Over-Temperature, Over-Cur-  
rent and Under-Voltage Lockout protections insure safe operation under  
abnormal operating conditions.  
Supported by PowerArchitect™ 5.2 or later  
APPLICATIONS  
Industrial Control Systems  
Automatic Test Equipment  
Video Surveillance Systems  
Automotive Infotainment  
The XR77129 is offered in a RoHS compliant, “green”/halogen free 44-pin  
TQFN package.
