Isolated
DC-to-DC Converter
Description:
M57140-01 is an isolated DC-to-DC
converter designed to drive IPMs
(Intelligent Power Modules). With
an input of DC 20V, the module
supplies four 15V outputs. Isolation is provided from primary to
secondary and also between the
secondaries. Interwinding isolation
is designed for driving the IPM.
Features:
□ Output Specification:
+15V x 4, Total 3W max.
□ Primary-to-secondar y Isolation:
2500 V
□ Secondary-to-secondary
Isolation V oltage:
1500 V
□ Compact, Low Profile Design
