Linear Technology LTM8046 Demo Application Manual

DESCRIPTION

The demo circuit 1559A features the
2.5W isolated flyback μModule
circuit is designed for a 5V output from a 3.2V to 26V
input. The typical current capability of the 5V output varies
with input voltage from about 150mA at V
550mA at V = 26V. R2 provides the necessary minimum
IN
load current to keep the V
entire input voltage range. Please see the Typical Perfor-
mance Characteristics curves in the LTM8046 data sheet
to determine the minimum load current for other input/
output configurations.
