R12P21503D
15W isolated DC-DC converter with 9-36V input and dual 15V outputs in DIP package.
Product Overview
Description
The R12P21503D from Recom is a versatile 15W isolated DC-DC converter designed for analog and mixed-signal applications requiring bipolar power supplies. The 4:1 input voltage range (9-36VDC) accommodates both 12V and 24V nominal systems, making it ideal for industrial automation and battery-powered equipment. The dual outputs provide +15V and -15V at 500mA each, perfect for powering operational amplifiers, data converters, and analog front-end circuits. The 1600VDC isolation voltage ensures safety and noise immunity in industrial environments. The DIP-24 package (32.0 x 20.3 x 10.2mm) offers excellent thermal performance and easy through-hole assembly. With efficiency up to 88%, the R12P21503S minimizes power dissipation and heat generation. The converter includes comprehensive protection features: continuous short circuit protection, overcurrent limiting, and overtemperature shutdown. The wide operating temperature range (-40°C to +85°C) without derating ensures reliable operation in harsh industrial environments. The R12P21503D meets UL/EN/IEC 62368-1 safety standards and is suitable for industrial, telecommunications, and test equipment applications. Remote on/off control allows power sequencing and energy management in complex systems.

Frequently Asked Questions
Can I use only one output of the dual converter?
Yes, you can use only the positive or negative output. However, for optimal regulation and performance, it's recommended to load both outputs symmetrically. If using only one output, minimum load requirements may apply to the unused output - consult the datasheet.
For single-output applications, consider a single-output converter for better efficiency and lower cost.
What is the cross-regulation between outputs?
The R12P21503D features excellent cross-regulation of ±5% typical. This means a load change on one output has minimal effect on the other output voltage. For critical analog applications, this ensures stable bipolar supplies.
For precision analog circuits, verify cross-regulation meets your requirements under actual load conditions.
How do I use the remote on/off control?
The remote on/off pin allows external control of the converter: Open or high (>3.5V): Converter ON; Low (<0.8V): Converter OFF. This can be driven by a logic signal, optocoupler, or switch. When disabled, the converter draws minimal quiescent current (<1mA).
Use remote on/off for power sequencing, energy management, or safety shutdown functions.
