STEVAL-ISA102V2 STMicroelectronics

S T E VA L - I S A 1 0 2 V 2 80 W high performance transition mode PFC evaluation board based on L6562A Data brief Description The L6562A is a current-mode PFC controller operating in transition mode (TM). With the same pinout as its L6562 predecessor, the L6562A offers improved performance mainly in terms of efficiency and noise immunity. The STEVAL-ISA102V2 implements an 80 W, wide-range mains input and a PFC pre- conditioner suitable for lighting, adapters, consumer smps, etc. Features Line voltage range: 88 to 265 VAC Minimum line frequency (fL): 47 Hz Regulated output voltage: 400 V Rated output power: 80 W Maximum 2f output voltage ripple: 10 V pk- L pk Hold-up time: 20 ms (VDROP after hold-up time: 300 V) Minimum switching frequency: 35 kHz Minimum estimated efficiency: 92% (VIN = 90 V , P = 80 W) AC OUT Maximum ambient temperature: 50 C PCB type and size: single-side, 35 m, CEM-1, 108 x 57 mm RoHS compliant September 2016 DocID029799 Rev 1 1/4 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram STEVAL-ISA102V2 1 Schematic diagram Figure 1: STEVAL-ISA102V2 circuit schematic GSPG2809161015SG 2/4 DocID029799 Rev 1 Vo=400V D1 NTC Po=80W STTH1L06 2.5 T1 R4 R5 D8 C5 R14 R11 272700 kk 272700 kk 11NN44114488 1010 nFnF 100100 1M R50 - 22 k D2 R1 R12 1N5248B 1 M 1M R6 C3 - 2200 nF 47 k C1 P1 C23 00.2222 FF 150 nF ZCD COMP INV + W08 F1 630V C6 4A/250V R2 VCC 8 5 2 1 47 F R7 1 M 33 450V Q1 MULT GD 3 7 Vac - L6562A STF7N60M2 88V 6 4 to R8 264V 47k GND CS C2 R15 10nF C29 SHORTED R3 C4 22 F R9 R10 15 k 100 nF R13 R13B 25V 0.68 0.68 15 k 82 k 0.25W 0.25W Boost Inductor Spec (ITACOIL E2543/E) E25x13x7 core, N67 ferrite 1.5 mm gap for 0.7 mH primary inductance Primary: 102 turns 20x0.1 mm Secondary: 10 turns 0.1 mm
