1.22V  
The UCC39421 family of synchronous  
RESET  
UCC39422

PWM controllers is optimized to operate  
from dual alkaline/NiCd cells or a single  
Lithium-Ion (Li-Ion) cell, and convert to  
adjustable output voltages from 2.5 V to  
8 V. For applications where the input  
voltage does not exceed the output, a  
standard boost configuration is used.

For other applications where the input voltage can swing above and below the output, a 1:1 coupled inductor  
(Flyback or SEPIC) is used in place of the single inductor. Fixed frequency operation can be programmed, or  
synchronized to an external clock source. In applications where (at light loads) variable frequency mode is  
acceptable, the IC can be programmed to automatically enter PFM (pulse frequency modulation) mode for an  
additional efficiency benefit.  
Synchronous rectification provides excellent efficiency at high power levels, where N- or P- type MOSFETs can  
be used. At lower power levels (between 10% and 20% of full load) where fixed frequency operation is required,  
low power mode is entered. This mode optimizes efficiency by cutting back on the gate drive of the charging  
FET. At very low power levels, the IC enters a variable frequency mode (PFM). PFM can be disabled by the user.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
