5V/2A High Voltage, Off-Line Digital PWM Controller with Integrated BJT Evaluation Board
Overview
| Topology | Flyback Converter |
| Input voltage | 90-264 V |
| Output 1 | 5 V / 2 A |
| IC revision | 0.1 |
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.
