DESCRIPTION
When board space is at a premium and voltage conversions require low power the LAN F series miniature
converters offer superior performance for an economical price. A multitude of options and operating ranges allow
you to custom-tailor these converters to your application requirements. These dc/dc converters provide up to 1.8
watts of power while maintaining specifications over the entire commercial operating temperature range.
