FEATURES

● UP TO 85% EFFICIENCY

● THERMAL PROTECTION

● DEVICE-TO-DEVICE SYNCHRONIZATION

● SHORT-CIRCUIT PROTECTION

● EN55022 CLASS B EMC PERFORMANCE

● UL1950 RECOGNIZED COMPONENT

● JEDEC PDIP-14 AND GULL-WING PACKAGES

DESCRIPTION

The DCV01 series is a family of 1W, 1500Vrms

isolated, unregulated DC/DC converters. Requiring a

minimum of external components and including on-

chip device protection, the DCV01 series provides

extra features such as output disable and synchroniza-

tion of switching frequencies.

The use of a highly integrated package design results

in highly reliable products with a power density of

40W/in

(2.4W/cm

). This combination of features,

high isolation, and small size makes the DCV01 suit-

able for a wide range of applications.

APPLICATIONS

● INDUSTRIAL CONTROL AND

INSTRUMENTATION

● POINT-OF-USE POWER CONVERSION

● GROUND LOOP ELIMINATION

● DATA ACQUISITION

● TEST EQUIPMENT

● SECONDARY ISOLATION CIRCUITS

switching frequency, or even stopping the oscillator circuit. If synchronized devices are used, it should be noted that, at start up, all devices will draw maximum current simultaneously. This can cause the input voltage to dip and should it dip below the minimum input voltage (4.5V), the devices may not start up. A 2.2µF capacitor should be connected close to the input pins. If more than eight devices are to be synchronized, it is recommended that the SYNCIN pins are driven by an external device.
PAGE 8
The DCV01 is a switching power supply and as such can place high peak current demands on the input supply. In order to avoid the supply falling momentarily during the fast switching pulses ground and power planes should be used to track the power to the input of DCV01. If this is not possible then the supplies must be connected in a star formation with the tracks made as wide as possible. If the SYNCIN pin is being used then the tracking between device SYNCIN pins should be short to avoid stray capacitance.
