Uses of LEDs continue to expand rapidly


LED Lighting Market profile

Applications are numerous and varied.

There may be thousands of end-users Worldwide;

most having annual volumes of less than 50k.

Many end-users do not have technical expertise in

selecting LEDs and in optimizing optical efficiencies.

Many end-users do not have design expertise in

driver circuits.

Most end-users are dependent on contractors to

assemble the LEDs and/or the driver assemblies.


Why do we need electronics to drive LEDs?

At this stage you might want to involve your FAE to help you identify

the proper device. Local ON Semiconductor FAEs and the Technical

Support Center (tel: +421 33 790 2910 )are also available to answer

any question you might have

•What LED lighting application is your customer trying to power up?

•Are they designing their own electronic control system?

•What level of Power and Voltage do they need?

•Do they have an existing solution? What device do they use?

•What are the main driver(s) for their new design (cost, efficiency,

other…) ?

•What volume (annual run rate) and time line (production start) do

they have in mind?

Current-Mode Fixed Frequency Operation: 65 kHz / 100 /130 kHz

Fixed peak Current: 450 mA (NCP1074) & 250 mA (NCP1072)

Auto-recovery over power protection or short circuit protection.

Internal current source for lossless startup sequence.

1 ms soft start

Internal Temperature Shut Down (TSD)

Vcc OVP when the clamp current on VCC pin is above 8.5 mA

Frequency jittering always present

Fixed ramp compensation

Double Start-up current level (Short on the Vcc)

Line detection to avoid hiccup after turning off

Frequency Foldback in light load and then Skip mode
