FEATURES  
APPLICATIONS  
•
•
•
Single Supply Operation: 4.5 V to 20 V  
Output Voltage from 0.6 V to 5.6 V  
•

PMBus Capability  
DESCRIPTION  
The TPS40422 is a dual-output PMBus synchronous  
buck controller. It can be configured also for a single,  
two-phase output.  
–
–
–
–
Margining Up/Down with 2-mV Step  
Programmable Fault Limit and Response  
Output Voltage, Output Current Monitoring  
External Temperature Monitoring with  
2N3904  
Its wide input range can support 5-V and 12-V  
intermediate buses. The accurate reference voltage  
satisfies the need of precision voltage to the modern  
ASICs and potentially reduces the output  
capacitance. Voltage mode control is implemented to  
reduce noise sensitivity and also ensures low duty  
ratio conversion.  
–
–
Programmable UVLO ON/OFF Thresholds  
Programmable Soft Start Time and Turn  
On/Off Delay  
•
On-Chip Non-volatile Memory (NVM) to Store  
Custom Configurations  
Using the PMBus protocol, the TPS40422 margining  
function, reference voltage, fault limit, UVLO  
threshold, soft start time and turn on/off delay can be  
programmed.  
•
•
180° Out-of-Phase to Reduce Input Ripple  
600-mV Reference Voltage with ±0.5%  
Accuracy from 0°C to 85°C  
•
•
Inductor DCR Current Sensing  
In addition, an accurate measurement system is  
implemented to monitor the output voltages, currents  
and temperatures for each channel.  
Programmable Switching Frequency from  
200 kHz to 1 MHz  
•

•
Voltage Mode Control with Input Feed Forward  
Current Sharing for Multiphase Operation  
Supports Pre-biased Output  
Differential Remote Sensing  
External SYNC  
BPEXT Pin Boosts Efficiency by Supporting  
External Bias Power
