Ultra Low Noise, Ultra Compact, Isolated type DC-DC Converter
b
6Watt BLC12 Series
The BLC series isolated-type DC-DC converters feature a small package
(23.2x21.1x9.7mm) and light weight (5.4g) capable of 6W output.
As ultralow noise and extremely high efficiency are made possible by a new circuit,
it is ideal for an analog circuit as well as an analog and digital hybrid circuit.

Note 1: Output voltage in parentheses is when Vadj and –Vout are short-circuited.
Note 2: Output current in parentheses is at the maximum output voltage.
Note 3: Ripple noise and efficiency are at 12V input voltage and load rating.
Note 4: Ripple noise is measured at 20MHz bandwidth, with a multi layered ceramic capacitor with 10μF at
input and 0.47μF at output
(Temperature derating
required)
- RoHS Compliant
