S T E VA L - I S A 1 3 2 V 1 300 W peak power (170 W continuous power) LLC resonant converter based on L6699, STB13N60M2 and STPS20H100CG Data brief Continuous power at 30 C ambient temperature:170 W The power MOSFETs and diodes are both in DPAK packages RoHS compliant Description The STEVAL-ISA132V1 evaluation board implements a converter capable of delivering 170 W of continuous power (V = 190 VAC to 264 IN VAC, VOUT = 24 V) and more than 300 W peak power for a limited time. The architecture of the board is based on a single-stage LLC resonant converter without PFC using the new L6699 resonant controller. The L6699 integrates some very innovative functions such as self-adjusting adaptive dead-time, anti-capacitive mode protection and proprietary safe-start procedure preventing hard switching at startup. High efficiency at full load (> 92%) and no load (< 0.6 Features W) is obtained thanks to the STB13N60M2 (600 V, 0.35 W typ., 11 A) MDmesh M2 power Input mains range: 190 to 264 VAC - frequency 50 Hz MOSFET in the half-bridge, and the STPS20H100CG (V = 100 V, I (AV) = 2 x 10 RRM F Output voltage: 24 V 5% A) Schottky diode for secondary rectification. No-load consumption: < 0.6 W Efficiency 230 VAC > 92% EMI: within EN55022 Class-B limits conducted pre-compliance Safety: meets EN60950-1 Dimensions: 90 x 90 mm, 50 mm component maximum height Safe startup procedure to avoid hard switching Hard switching prevention in overload condition and low load condition Burst mode in low load condition with smooth restart to prevent audible noise Evaluation board can deliver more than 300 W peak power for a limited time by a thermal protection NTC positioned near output diodes May 2015 DocID026808 Rev 2 1/4 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram STEVAL-ISA132V1 1 Schematic diagram Figure 1: STEVAL-ISA132V1 circuit schematic 2/4 DocID026808 Rev 2
