EVL6699-90WADP 19 V - 90 W adapter with PFC for laptop computers based on the L6563H and L6699 Data brief Features ■ Universal input mains range: 90 - 264 VAC frequency 45 - 65 Hz ■ Output voltage: 9 V at 4.75 A continuous operation ■ Mains harmonics: meets EN61000-3-2 ClassD and JEITA-MITI Class-D ■ No load mains consumption: according to ENERGY STAR® 2.0 for external power supplies ■ Average efficiency: according to ENERGY STAR 2.0 for external power supplies ■ Light load efficiency: according to ErP Lot 6 Tier 2 requirements mode protection and proprietary “safe-start” procedure preventing hard switching at startup. ■ EMI: within EN55022-Class-B limits ■ Safety: meets EN60950 ■ Dimensions: 65 x 151 mm, 25 mm component maximum height ■ PCB: double-side, 70 µm, FR-4, mixed PTH/SMT The PFC stage works as pre-regulator and powers the resonant stage with a constant voltage of 400 V. The downstream converter operates only if the PFC is working and regulating its output voltage. In this way, the resonant stage can be optimized for a narrow input voltage range improving the efficiency of the primary side power components. Description The architecture of the EVL6699-90WADP is based on a two-stage approach; a front-end PFC pre-regulator based on the L6563H TM PFC controller and a downstream LLC resonant half bridge converter using the new L6699 resonant controller. Thanks to the chipset used, the main features of this design are very high efficiency, compliant with ENERGY STAR eligibility criteria (EPA rev. 2.0 EPS) and very good efficiency at light load too, compliant with the new ErP Lot 6 Tier 2 requirements. No-load input power consumption is also very low, well within the international regulation limits. EVL6699-90WADP The transformer uses the integrated magnetic approach, incorporating the resonant series inductance. Therefore, no external, additional coil is needed for the resonance. The transformer configuration chosen for the secondary winding is centre tap. The controller of the LLC stage is the L6699, integrating innovative functions such as selfadjusting adaptive deadtime, anti-capacitive July 2012 Doc ID 023378 Rev 1 For further information contact your local STMicroelectronics sales office. 1/5 www.st.com 5 # N& Doc ID 023378 Rev 1 2 2 2 + # N& 2 -EG # U& 2 + 2 + # N& + 2 # N& ^ # N& # U& 2 2 + 2 2 + .# 07-,!4#( (63 0&#/+ $ 07-34/0 4"/ :#$ 25. 6&& '.$ -5,4 #3 '$ 6## 5 ,( 2 + ? #/-0 ).6 2 + 0#"2%6 : # P& # 2 N& + 2 - 2 - $ '"5* # P& # N& 2 2 2 2 2 + .# 2&-).
