Features

Unregulated

Converters

• 2W dual output converter

• Industry standard SIP7 packages

• Power sharing on outputs

• Optional continuous short circuit protection

• 1kVDC and 2kVDC basic isolation

• UL94 V-0 package material

• Efﬁciency up to 87%

Description

The RD series have been speciﬁcally designed for applications where dual power rails need to

be created from a single rail supply and a low cost solution is required. With efﬁciencies up to 87%,

the full output power is available over the operating temperature range -40°C to +85°C and

the converters can be used in ambient temperatures of up to 100°C with derating. The wide selection

of industry standard input voltage and output voltage options plus an input to output isolation of 1kVDC

or 2kVDC makes these converters suitable for many industrial applications.

Model Numbering

Notes:

Note3: standard part is without Continuous Short Circuit Protection

add sufﬁx „/P“ for Continuous Short Circuit Protection

Note4: add sufﬁx „/H“ for 2kVDC Isolation

or add sufﬁx „/HP“ for Continuous Short Circuit Protection and 2kVDC Isolation

Ordering Examples:

RD-123.3D/P: 12V Input Voltage, ±3.3V Output Voltage, Dual Output with continuous short circuit protection

RD-0509D/HP: 5V Input Voltage, ±9V Output Voltage, Dual Output with 2kVDC Isolation and continuous short circuit protection

Notes:

Note1: Efﬁciency is tested at nominal input and full load at +25°C ambient

Note2: Max Cap Load is tested at nominal input and full resistive load and is deﬁned as the

capacitive load that will allow start up in under 1s without damage to the converter
