Product details
Overview
EVL6599A-90WADP from STMicroelectronics is a 90 W, two-stage AC-DC demonstration board featuring an L6563H-based PFC pre-regulator and an L6599A-controlled LLC resonant half-bridge converter for laptop adapters. It delivers 19 V at 4.75 A, achieves >90% full-load efficiency, maintains <0.3 W no-load input power, and complies with ENERGY STAR® EPS v2.0 and EN61000-3-2 Class-D.
For engineers reviewing the EVL6599A-90WADP datasheet, EVL6599A-90WADP application, EVL6599A-90WADP functional block diagram, or EVL6599A-90WADP design reference, this board provides validated implementation guidance for high-efficiency, low-standby-power, wide-input-range adapter designs targeting portable computing power supplies.
Technical Context
The board implements a master-slave startup sequence where the L6563H PFC stage powers up first and enables the L6599A LLC stage only after establishing a stable 400 V bulk voltage. Brownout protection is implemented via dual thresholds: L6563H RUN pin (90 Vac typ. turn-on) and L6599A LINE pin (380 V turn-on / 300 V turn-off).
L6599A operates with fixed 50% duty cycle and variable-frequency control (≈100–130 kHz), using internal soft-start timing (R44/C18), burst-mode operation below ~15 W load (via STBY pin), and lossless primary current sensing (ISEN pin, 0.8 V threshold) for overload/short-circuit protection with programmable delay (C45/R24).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Power | 90 W continuous (19 V @ 4.75 A), validated across 90–264 Vac input range. |
| Full-Load Efficiency | 92.53% at 230 Vac / 50 Hz; 90.75% at 115 Vac / 60 Hz - exceeds ENERGY STAR® v2.0 minimum (87%). |
| No-Load Input Power | 0.246 W at 230 Vac - well below ENERGY STAR® 0.5 W limit and EN60950 standby requirements. |
| Switching Frequency Range | Programmable 100–130 kHz via RFMIN pin resistor network (R31/R34), optimized to minimize light-load switching losses. |
| EMI Compliance | Meets EN55022 Class-B conducted emissions; harmonic current meets EN61000-3-2 Class-D and JEITA-MITI Class-D. |
| Protection Functions | Integrated brownout (dual-stage), overcurrent (lossless ISEN sensing), short-circuit (intermittent burst restart), PFC open-loop latch, and thermal-safe operation. |

FAQ
What is the primary function of the EVL6599A-90WADP board?
The EVL6599A-90WADP is a complete, tested 90 W AC-DC adapter reference design. It integrates ST's L6563H PFC controller and L6599A LLC resonant controller to deliver regulated 19 V output with >90% efficiency, <0.3 W no-load consumption, and full compliance to ENERGY STAR® v2.0, EN61000-3-2, and EN55022 standards - intended for rapid prototyping and design validation.
Does this board include both PFC and LLC stages?
Yes. The board implements a two-stage architecture: a front-end boost PFC stage using the L6563H controller (regulated 400 V output) feeding an isolated LLC resonant half-bridge stage controlled by the L6599A. The stages are interlocked - the LLC stage only operates when the PFC has stabilized its output voltage, enabling narrow-input optimization and improved efficiency.
Can EVL6599A-90WADP be used for regulatory pre-compliance testing?
Yes. The board has undergone conducted emission pre-compliance testing per EN55022 Class-B (Figures 18–19), harmonic current verification per EN61000-3-2 Class-D and JEITA-MITI Class-D (Figures 5–6), and thermal mapping under full-load conditions (Figures 16–17), making it suitable for early-stage EMI and safety validation prior to formal certification.
What protection features are implemented on this board?
The board implements brownout protection (L6563H RUN pin, L6599A LINE pin), lossless overcurrent/short-circuit detection (L6599A ISEN pin with 0.8 V threshold and C45/R24 delay timing), PFC open-loop latching (via PFC_OK/DIS pins), and burst-mode standby control (L6599A STBY pin, active below ~15 W). All protections are hardware-verified and documented in AN3172 Sections 1.2, 1.6, 1.7, and 1.8.
