42V, 350mA Synchronous  
Step-Down Regulator with  
2.5µA Quiescent Current  
FEATURES  
DESCRIPTION  
The LT®8606 is a compact, high efficiency, high speed  
synchronous monolithic step-down switching regulator  
that consumes only 1.7µA of non-switching quiescent  
current. The LT8606 can deliver 350mA of continuous  
current. Low ripple Burst Mode operation enables high  
efficiency down to very low output currents while keeping

Fast Minimum Switch-On Time: 35ns  
Adjustable and Synchronizable: 200kHz to 2.2MHz  
Spread Spectrum Frequency Modulation for Low EMI

Low Dropout  
Peak Current Mode Operation  
Accurate 1V Enable Pin Threshold  
Internal Compensation  
Output Soft-Start and Tracking  
P-P  
with peak current mode topology allows the use of small  
inductors and results in fast transient response and good  
loop stability. The EN/UV pin has an accurate 1V threshold  
and can be used to program V undervoltage lockout or  
to shut down the LT8606. The PG pin signals when V  
is within 8.5% of the programmed output voltage as well  
as fault conditions.  
IN  
OUT  
The MSOP package includes a SYNC pin to synchronize  
to an external clock, or to select Burst Mode operation  
or pulse-skipping with or without spread-spectrum; the  
TR/SS pin programs soft-start or tracking. The DFN pack-  
age omits these pins and can be purchased in pulse-skip-  
ping or Burst Mode operation variety.
