Single Stage Offline LED Driver
DESCRIPTION
The EV44010-S-00B is a single stage offline
evaluation board of MP44010 and MP26085 for
30W LED lighting driver.
MP44010 is a boundary conduction mode PFC
controller which can provide simple and high
performance active power factor correction
using minimum external components.
MP26085 is a controller which can provide
constant current control and over voltage

QUICK START GUIDE
1. Preset AC input voltage between 85V and 265V. Then turn off AC power supply.
2. Connect the LED string to the LED+ and LED- pins.
3. Connect the Line and Neutral terminals of the power supply output to AC input.
4. Turn the power supply on. The board will automatically startup.
5. The LED dimming function is available with two options (PWM dimming & 0-10V dimming). For
PWM option, R31=0Ω and R35 is NS; apply a square voltage (V
H
=5V, V
L
=0V, Duty=50%) to the
pillars of PWM DIM and GND. For 0-10V option, R35=0Ω and R31 is NS; apply a DC voltage (0-
10V) to the pillars of 0-10V DIM and GND.

QUICK START GUIDE
1. Preset AC input voltage between 85V and 265V. Then turn off AC power supply.
2. Connect the LED string to the LED+ and LED- pins.
3. Connect the Line and Neutral terminals of the power supply output to AC input.
4. Turn the power supply on. The board will automatically startup.
5. The LED dimming function is available with two options (PWM dimming & 0-10V dimming). For
PWM option, R31=0Ω and R35 is NS; apply a square voltage (V
H
=5V, V
L
=0V, Duty=50%) to the
pillars of PWM DIM and GND. For 0-10V option, R35=0Ω and R31 is NS; apply a DC voltage (0-
10V) to the pillars of 0-10V DIM and GND.
