Summary and Features
• Extremely small form factor, fits within GU10 lamp base
• Operates over the universal input voltage range (85 – 265 VAC)
• Meets EN55022 B conducted EMI requirements
• Drives LEDs in constant current (CC) mode
• Built-in, output overvoltage protection when unloaded
• Low parts count, low-cost solution: only 25 components
• Non-isolated buck converter configuration allows use of off-the-shelf inductors
• Allows supply to be tested without the load connected
(does not require a custom transformer)
