80 W offline LED driver with PFC

1

Introduction

The use of high power LEDs in lighting applications is becoming increasingly popular due to

rapid improvements in lighting efficiency, longer life, higher reliability and overall cost

effectiveness. Dimming functions are more easily implemented in LEDs, and they are more

robust and offer wider design flexibility compared to other light sources.

For this reason a demonstration board for driving high brightness and power LEDs has been

developed. The STEVAL-ILL013V1 demonstration board is an 80 W offline dimmable LED

driver with high power factor (PF) intended for fixed number of LEDs, the overall design of

which is described in detail in this user manual.

The LED current can be set to 350 mA, 700 mA and 1000 mA, using jumpers. Additionally,

a dimming function using a PWM (pulse width modulation) signal is implemented as well,

allowing the user to set the LED brightness from 0% up to 100%. The demonstration board

can be ordered using order code STEVAL-ILL013V1, and is shown in Figure 1.

STEVAL-ILL013V1 main features

■ 80 W LED driver

■ 350 mA, 700 mA and 1 A LED current settings

■ High efficiency (~90%)

■ Wide input voltage range: 88 to 265 VAC

■ High power factor: 0.99 for 110 VAC and 0.98 for 230 VAC

■ Universal PWM input for dimming (external board required)

■ Non-isolated SMPS

■ Brightness regulation between 0% and 100%

■ EMI filter implemented

■ EN55015 and EN61000-3-2 compliant
