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

• Allows supply to be tested without the load connected

• Low parts count, low-cost solution: only 25 components

• Non-isolated buck converter configuration allows use of off-the-shelf inductors

(does not require a custom transformer)

The products and applications illustrated herein (including circuits external to the products and transformer

construction) may be covered by one or more U.S. and foreign patents or potentially by pending U.S. and foreign
