Sanken LC5222D
The LC5220 uses constant current mode precision and simplifies setting of current level • Sleep function, with latch mode; input high, 3 V or more, on REF pin turns off IC output to LEDs • Enable function; input low on REF pin toggles IC output to LEDs • High input voltage; up to 250 V or 450 V, depending on product • Output Current: 0.5A to drive LEDs.| Part No. | LC5222D |

FEATURES AND BENEFITS
DESCRIPTION
● Buck and buck-boost topology; selectable by peripheral LC5220 series is a non-isolating, simple and efficient LED circuit structure driver. The high voltage capability allows direct connection● Built-in fixed reference voltage limiting constant current to a wide range of supply voltages ranging from 25 to 400 V control; high precision regulator improves current (recommended). and buck and buck-boost voltage converters can be configured. ns A power MOSFET and controller IC are incorporated in one package. Because few external parts are required, the ig LC5220 is ideal for use in small-size LED light bulbs. es Various control requirements can be supported through the D REF pin, including peak current control, output on/off, and
● Built-in constant current control; PWM method, output current adjustable by the voltage input on the REF pin w
● External adjustable PWM dimming control e
● Protection features: N ▫ Open protection (OPP) with latched shutdown...
