36V, 1A Step-Down

µModule Regulator 

Demonstration circuit 1261A features the LTM

®

8022 step-

down μModule

®

 regulator delivering a 3.3V output from a 

4.5V to 36V input supply. As a step-down converter, the 
LTM8022 requires a minimum amount of headroom to keep 
the output in regulation. The device may be synchronized 
to an external clock or allowed to enter low ripple Burst 
Mode

®

 operation at light load conditions by applying the 

appropriate signal to the SYNC pin. Current sharing with 
another LTM8022 is enabled by tying the VIN, VOUT and 
SHARE pins together to support higher output loads.
