STEVAL-ILL042V2 60 W, high power-factor flyback LED driver based on the L6562AT and TSM101 Data brief Description The STEVAL-ILL042V2 demonstration board is an LED power supply in high PF flyback configuration designed to drive a 60 W LED array. The board is based on the L6562AT and the TSM101 controller. This configuration uses an isolated feedback with an optocoupler and a secondary side reference/error amplifier, the TSM101, for voltage and current regulation. STEVAL-ILL042V2 The TSM101 includes two op-amps. One op-amp is used for constant voltage control and the other for constant current control. Features The L6562AT is a PFC controller which operates in transition mode. The highly linear multiplier Mains voltage range: V = 185, V AC(min) AC(max) includes a special circuit which is able to reduce = 265 AC input current distortion, allowing wide-range Minimum mains frequency: f = 47 Hz mains operation with an extremely low THD, even L over a large load range. DC output voltage: V = 130 V OUT Maximum output current: I = 0.462 A Efficiency is high at heavy load - more than 90% OUT can be achieved. Minimum switching frequency: f =57Hz Designed using the L6562A and the TSM101 SW(min) controllers, this system offers several advantages Reflected voltage: V = 195 V R in terms of output current and voltage stability. Leakage inductance spike: V = 100 V SPIKE Expected efficiency: 92% RoHS compliant September 2013 DocID025325 Rev 1 1/4 For further information contact your local STMicroelectronics sales office. www.st.comSchematic diagram STEVAL-ILL042V2 1 Schematic diagram Figure 1.
