SEM5027A LED driver

Description

The LED driver IC is focused on effectively driving and controlling the LED, which is usually used in the backlight unit (LCD TV, Monitor). The SEMCO LED Driver IC provides a high contrast ratio through the DC – DC conversion and dimming control. Depending on the controlling method, it either supports the linear type or the switching type topology.

Features

1. LED Driver IC
2. LLC IC ( Flyback )

UDN6118A Datasheet

Description

Consisting of eight NPN Darlington output stages and the associated common-emitter input stages, these drivers are designed to interface between low-level digital logic and vacuum fluorescent displays.

Both devices are capable of driving the digits and/or segments of these displays and are designed to permit all outputs to be activated simultaneously. Pull-down resistors are incorporated into each output and no external components are required for most fluorescent display applications.

 

With any device, the output load is activated when the input is pulled towards the positive supply (active ‘high’). The UDN6118A is furnished in a standard 18-pin plastic DIP; the A6118SLW is in a 20-
lead wide-body SOIC. Both units operate over the temperature range of -20°C to +85°C.

These devices are also available for operation over the temperature range of -40°C to +85°C by changing the part number to UDQ6118A or A6118ELW.
