DC-DC Converter

BDD20170524_A01

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.

■ Features

- Adjustable Output Voltage

- ON/OFF Control

- Dual power supply usable

as single power supply

- Withstand voltage AC500V

- Over Current Protection Circuit

- No tantalum capacitor or

electrolytic capacitor

- Covered with a metal shield

- Surface Mount Package

- No heat sink needed

- Operating Temp Range

-40°C to +85°C

(Temperature derating

required)

- RoHS Compliant

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
