LED Lighting IC

LC5226D

13 October 2011

◆Description

◆Package

Package: DIP8

LC5226D is non-isolated type driver IC for LED lighting

which can achieve high efficiency in simple circuitry. Its

compact package which includes output MOSFET and

controller, and low external components are suitable for

small lighting equipment which requires saving space, like

LED light bulb.

To meet various requirements, Buck-Boost operation

which has wide input/output capability is available. And

also, control functions with Ref input are implemented.

Its high voltage capability allows direct connection to

rectified AC supply.

Open protection for Buck-Boost operation and variable

OCP improve safeness.

◆Applications

 LED Lighting equipment

 LED Light bulb

◆Main Specification

MOSFET

Output Current

450V (MIN), 3.0Ω (MAX)

◆Features

 Buck-Boost operation

 DIP8 Package

In addition to normal Buck operation, Buck-Boost

operation which can both Step-up and down is also

available, to operate in wide input/output condition.

 Open protection for Buck-Boost operation

Protection circuit to prevent damage when load open

failure in Buck-Boost operation.

 Built-in reference voltage for current setting

Precision and easy current setting.

 Sleep function

Output MOSFET and controller are included in

one package.

 High voltage supply input

 Built-in constant current controller

- PWM mode current control circuitry.

- Adjustable output current by input voltage to Ref pin.

 External PWM Dimming

 Variable type over current protection (OCP)

- Latch type operation

Latch off the output by Ref pin input voltage.

 Disable function

- OCP threshold is adjusted by setting current and

temperature to ensure protection.

Shut off LED current by Ref pin input voltage.

 Under voltage lockout protection (UVLO)

 Thermal Shutdown protection (TSD)
