Product overview

Description

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.

  • All features

    • Input mains range: 190 to 264 VAC - frequency 50 Hz
    • Output voltage: 24 V 5%
    • 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
    • Continuous power at 30 °C ambient temperature:170 W
    • The power MOSFETs and diodes are both in D²PAK packages
    • RoHS compliant
