Eighth-Brick

TDK-Lambda’s hugely successful family of eighth brick
converters with the broadest range of output voltages
available has recently been augmented by the addition of
the new wide input voltage products, extending the scope
of applications to include ‘remotely powered’ RF devices
commonly found in latest LTE / GSM telecom equipment.

• 1500V basic isolation
• Low profile – contact cooling compatibility
• Good output voltage adjustment / trim range
• Remote sense
• Monotonic start – up
• Starts into pre – biased load
• Constant switching frequency
• Pin length choice, SMT options
• Positive or negative on / off logic option
