Ultra Low Noise, Ultra Compact, Isolated type DC-DC Converter
b
1.5Watt BLA12 Series
Our BLA series isolated-type DC-DC converters feature a small package
(14x20.3x9.7mm) and light weight (3.2g) capable of 1.5W 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 analog and digital hybrid circuit.
■ Features
- Ultra low noise
- Adjustable Output Voltage
- ON/OFF Control
- Dual power supply usable as
single power supply
- Withstand voltage AC500V
- Built-in Over Current

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.
- No tantalum capacitor or
electrolytic capacitor
- Covered with a metal shield
