L6599ADTR ST High-Voltage Half-Bridge Resonant LLC Controller
L6599ADTR is ST improved half-bridge resonant LLC controller shipped in tape-and-reel SOIC-16 surface mount package, optimized exclusively for series resonant half-bridge power topology with fixed 50% complementary out-of-phase gate driving and built-in dead time for reliable soft switching, featuring 8.85V~16V VCC supply range, -40°C to +150°C junction operating temperature and 600V-rated integrated high-side floating driver with embedded bootstrap DMOS diode eliminating discrete external bootstrap component, rated for up to 500kHz adjustable switching frequency via external RC oscillator while fully compliant with RoHS eco-pack standards for automated SMT mass production of medium-to-high wattage AC-DC power supplies.
ST High-Voltage Resonant Controller Features AND Applications
This resonant control IC integrates dual-tier overcurrent protection combining early frequency foldback and latched full shutdown to guard against short-circuit damage, configurable non-linear soft-start restricts startup inrush surge and suppresses output voltage overshoot, programmable light-load burst mode cuts standby power draw to satisfy low-energy efficiency norms, dedicated PFC interconnect pin synchronizes front-end power factor correction stage for coordinated fault shutdown, built-in UVLO pull-down for ±300mA/±800mA high/low side gate drivers plus independent latched DIS pin simplify external OVP and thermal shutdown circuit design with minimal peripheral BOM cost.
It acts as core control chip widely deployed inside LCD/PDP television power boards, desktop PC and entry-level server switching power supplies, industrial open-frame AC-DC adapters, telecom rectifier modules and medium-power offline electronic transformers, serving as mainstream LLC resonant solution for cost-sensitive high-efficiency power conversion designs ranging from 100W up to 400W rated output power across consumer and industrial power electronics sectors.
Alternative LLC power supply ICs
● FSFR2100XS(ON Semiconductor): Integrated resonant half-bridge power controller with identical SOIC footprint and matching LLC control logic for direct PCB drop-in substitution during ST part supply shortage.
● NCP1399ADR2G(ON Semiconductor): Cross-brand resonant controller featuring equivalent frequency modulation and multi-level fault protection to realize seamless second-source replacement on existing circuit layout.
● LD6599GS(Lontium): Domestic cost-effective resonant IC sharing same package outline and electrical parameters for low-cost mass-production alternative procurement.
