The MP26085 is a voltage and current control IC integrated a precision voltage reference and a current source, which is suitable for battery charger, second controller of switching regulator systems, and other types of application required an accurate voltage and current control systems. This IC compares the DC voltage and the current level at the output of a switching power supply to the voltage reference and current limitation, respectively. It provides a feedback through an opto-coupler to the PWM controller IC at the primary side. The current source is controlled externally, which can be used to modify the level of current limitation by offsetting the information coming from the current sensing resistor. It is available in an 8-pin SOT23 package.

EV44010-S-00B Evaluation Kit 30W Output, 85V-265V AC Input Single Stage Offline LED Driver
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 protection.
The board involves LED dimming functions with two different options. One is PWM dimming and the other is 0-10V dimming.
The EV44010-S-00B can meet the Class C standard of IEC61000-3-2 and EN55015 standard.
