DESCRIPTION
LTM8033:
36V
IN
, 3A Low EMI Step-Down
µModule Regulator
Demonstration circuit DC1623A features the LTM
®
8033, a
low-EMI EN55022 Class B certified step-down μModule
®
regulator, pre-configured for a 3.3V output from a 5.5V
to 36V input. The circuit supports other features of the
LTM8033 including synchronization to an external clock,
current sharing with another LTM8033 μModule regula-
tor, and burst mode operation for improved efficiency
