DESCRIPTION  
TPS54290/1/2 is a dual output fully synchronous buck  
converter capable of supporting applications with a  
minimal number of external components. It operates  
from a 4.5 V to 18 V input supply voltage, and  
supports output voltages as low as 0.8 V and as high  
as 90% of the input voltage.  
Integrated UVLO  
0.8 VREF With 1% Accuracy (0°C to 85°C)  
Internal Soft-Start  
TPS54290 – 5.2 ms  
TPS54291 – 2.6 ms  
TPS54292 – 1.3 ms  
Both high-side and low-side MOSFETs are integrated  
to provide fully synchronous conversion with higher  
efficiency. Channel1 can provide up to 1.5 A of  
continuous current, meanwhile, Channel2 supports  
up to 2.5 A.  
Dual PWM Outputs 180° Out-of-Phase  
Dedicated Enable for Each Channel  
Current mode control simplifies the compensation.  
The external compensation adds flexibility for the  
user to choose different type of output capacitors.  
Current Mode Control for Simplified  
Compensation  
External Compensation  
180° out-of-phase operation reduces the ripple  
current through the input capacitor, providing the  
benefit of reducing input capacitance, alleviating EMI  
and increasing capacitor life.  
Pulse-by-Pulse Overcurrent Protection,  
2.2 A/3.8 A Overcurrent Limit
