DESCRIPTION

The DCR01 family is a series of high-efficiency, input-

isolated, output-regulated DC/DC converters. In addition to

1W nominal, galvanically-isolated output power capability,

this range of DC/DCs offer very low output noise, thermal

protection, and high accuracy.

The DCR01 family is implemented in standard molded IC

packaging, giving standard JEDEC outlines suitable for

high-volume assembly.

The DCR01 is manufactured using the same technology

as standard IC packages, thereby achieving very high reli-

ability.

● POINT-OF-USE POWER CONVERSION

● DIGITAL INTERFACE POWER

● GROUND LOOP ELIMINATION

● POWER-SUPPLY NOISE REDUCTION

FUNCTIONAL DESCRIPTION If devices are synchronized, it should be noted that all devices will draw maximum current simultaneously at start up. This can cause the input voltage to dip. Should it fall below the minimum input voltage, the devices may not start up. A 2.2µF capacitor (low ESR) should be connected as close to the device input pins as possible for the 5V input devices, and a 0.47µF capacitor for the 12V and 24V devices.
PAGE 11
APPLICATION NOTES ERROR FLAG The DCR01 has an ERROR pin which provides a “power good” flag, as long as the internal regulator is in regulation. DCR01 SINGLE VOLTAGE OUTPUT The DCR01 can be used to provide a single voltage output by connecting, see Figure 1. The ERROR output signal will be pulled up to the value of VOUT for the particular DCR01 being used.
PAGE 12
If the SYNC pin is being used, the tracking between device SYNC pins should be short to avoid stray capacitance. If the SYNC pin is not being used it is advisable to place a guard ring (connected to input ground) around this pin to avoid any noise pick up. The output should be taken from the device using ground and power planes. This will ensure minimum losses. A good quality low ESR capacitor placed as close as practicable across the input will reduce reflected ripple and ensure a smooth start up.
