Infineon – IR3826M – OptiMOS™ IPOL voltage regulator
The IR3826M is an easy-to-use, fully integrated and highly efficient DC-DC regulator.
The onboard PWM controller and OptiMOSTM MOSFETs with integrated bootstrap diode make the IR3826M a small footprint solution, providing high-efficiency power delivery.
The IR3826M is a versatile regulator, operating with wide input and output voltage range, offering programmable switching frequency from 300 kHz to 1.5 MHz, and pro-viding three selectable over current limits.
It also features important protection functions, such as pre-bias start-up, thermally compensated current limit, over voltage protection and thermal shutdown to give re-quired system level security in the event of fault conditions.
Features
- Constant frequency operations (Gen3 VM PWM engine)
- OptiMOS™ 5 for enhanced efficiency
- ROHS fully compliant without exemptions
Benefits
- Pin compatible to previous generation IPOLs (IR3824/5/9)
- Risk free efficiency upgrade with OptiMOSTM 5 (efficiency im-provement > 2% peak and > 6% at 20 A)
Target applications
- Storage Applications
- Telecom & datacom applications
- Distributed Point of Load power architectures
Competitive advantage
Compared to alternative solutions in the same price range (and former IFX Gen3) this part offers higher efficiency to save power, allows cool operations without heatsink or airflow at high ambient temperature in thermally challenged applications and enable operations at 1MHz for higher density with good effi-ciency and thermal (up to 50% pcb size saving estimated for 1 MHz operations vs 600 kHz).
