STEVAL-ISA132V1:300 W peak power (170 W continuous power) LLC resonant converter based on L6699, STB13N60M2 and STPS20M80CG
![steval-isa132v1 image](/image/st/en.steval-isa132v1.jpg)
The STEVAL-ISA132V1 evaluation board implements a converter capable of delivering 170 W of continuous power (VIN = 190 VAC to 264 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 W) is obtained thanks to the STB13N60M2 (600 V, 0.35 W typ., 11 A) MDmesh M2 power MOSFET in the half-bridge, and the STPS20H100CG (VRRM = 100 V, IF(AV) = 2 x 10 A) Schottky diode for secondary rectification.
