Product details
Overview
EVAL6599-200W from STMicroelectronics is a fully assembled, tested 200 W evaluation board implementing a three-stage wide-input AC/DC power supply for LCD TV and flat-panel displays. It integrates an L6563-based PFC pre-regulator (400 VDC output), an L6599-controlled half-bridge LLC resonant converter (24 V/6 A and 12 V/5 A outputs), and a VIPer12A-E-based auxiliary flyback (5 V/1 A and 3.3 V/0.7 A). Measured efficiency exceeds 88% at full load with 90–264 Vac input.
For engineers reviewing the EVAL6599-200W datasheet, EVAL6599-200W pinout, EVAL6599-200W application, or EVAL6599-200W equivalent, this reference design delivers verified performance data for high-efficiency resonant SMPS development-including ZVS operation, EN61000-3-2 PFC compliance, <0.5 W no-load consumption, and thermal maps across 115/230 Vac full-load conditions.
Technical Context
The board implements a universal-input (90–264 Vac), three-stage architecture: a fixed-off-time (FOT) boost PFC stage using L6563 delivers regulated 400 VDC; a half-bridge LLC resonant DC/DC stage controlled by L6599 operates in zero-voltage switching (ZVS) mode at ~95 kHz to generate 24 V and 12 V outputs; and a VIPer12A-E flyback supplies 5 V and 3.3 V with independent startup capability.
Feedback regulation uses TL431-based optocoupler circuits for both main and auxiliary stages, with weighted resistive dividers monitoring multiple outputs simultaneously. Protection includes lossless primary current sensing for short-circuit response, dedicated LINE and STBY pins on L6599 for sequencing/brown-out control, and EN55022 Class B conducted emission compliance verified per AN2393 test reports.
Key Specifications

FAQ
What is the purpose of the STBY pin on the L6599 controller used in this board?
The STBY pin enables burst-mode operation during light-load conditions to reduce no-load power consumption. In EVAL6599-200W, it is not actively used; instead, system-level sequencing is managed externally via J3 Pin 9 (ST-BY signal), which controls auxiliary voltage (VAUX) delivery to enable or disable the PFC and resonant stages independently.
How does the board achieve EN61000-3-2 compliance?
Compliance is achieved through the L6563-controlled boost PFC stage operating in fixed-off-time (FOT) mode, using voltage feed-forward (VFF) and precise current shaping. The design incorporates differential-mode filtering (C5/C6/L3), optimized coil selection (PQ35-900uH), and active harmonic current control-verified in AN2393 test results up to 264 Vac.
Can the +24 V and +12 V outputs operate without the auxiliary flyback stage?
No-the PFC and resonant stages rely on VAUX supplied from the auxiliary flyback's primary-side winding (T2). If J3 Pin 9 is left floating, only +5 V and +3.3 V are available; pulling Pin 9 to ground enables VAUX delivery to U1 (L6563) and U2 (L6599), allowing full 200 W operation.
What thermal performance data is provided for this evaluation board?
AN2393 includes infrared thermal maps for both 115 Vac and 230 Vac at full load (Figures 16 and 17), showing peak temperatures below critical thresholds for key components: MOSFETs Q5/Q6, diodes D8A/D8B, and transformer T1. No forced airflow was used; measurements were taken after 30 minutes of steady-state operation.
