Description

Evaluation Board for 10W Single-OutputSwitch-Mode Power Supply.The iW1818-EVAL evalution board provides a working and tested solution for a 10W power supply based on the iW1818, a PrimAccurate™ digital off-line power supply controller IC with integrated power switch from Dialog. With an integrated 800V power BJT transistor, the iW1818 provides a low total BOM cost and through the advanceddigital control technology, it removes the need for external secondary-side feedback components, further reducing component count and cost while improving reliability.

Characteristics

  • Wide input voltage range: 90VAC to 264VAC●● Output voltage: 5V ●● Output current: 2A●● Total output power: 10W max.●● Integrated 800V BJT●● Active mode efficiency > 80%●● Supports high capacitance loads up to 6,000mF●● Low no-load power: < 50mW (at 230 VAC)
