STEVAL-ILH002V1

STEVAL-ILH002V1 35 W electronic ballast for HID metal halide lamp Data brief Features ■ Vin (VAC) = 220 V ■ Efficiency = 86% ■ Pi = 41.5 W ■ THD = 20% ■ PF = 0.96 ■ Very good power regulation vs. voltage and/or current variation (using “fully analog SUM method”) ■ Cost-effective solution ■ RoHS compliant STEVAL-ILH002V1 Description The STEVAL-ILH002V1 demonstration board represents an electronic ballast for HID lamp. Unlike fluorescent lamps, HID lamp ballasts must be specifically designed for the lamp type and wattage used. HID lamps require a warm-up period to achieve full light output, and in some cases require several minutes before they can be re-ignited after they have been turned off. Metal halide lamps offer high efficacy, excellent color rendition, long service life, and good lumen maintenance. They are often used in outdoor applications and commercial interiors. The dimensions of the board are: W 76.55 mm, L 113 mm February 2010 Doc ID 17003 Rev 1 For further information contact your local STMicroelectronics sales office. 1/4 www.st.com 4 STEVAL-ILH002V1 schematic circuit Figure 1. *   #/. & &53 % # N& 6AC ,    8-(! $ $ $ $ N& 6 # P& # 2 + # N& 6 # #/-0 ). 6 —( 2 + 2 + 2 K  $ 344(2! # PIN 2  6REF 2 $ ,, $ ,, # 2  1 $  1 N& 6 344(! # 2 1 342 6CC   $ 344(25 $ 344(2! 1 +%! $ 344(! $ 344(! # N&6 340.+:    344(25 $ %&$ 4 # —& 6     1 ,, $ $ 6REF 2 7 2 # 2 K  1 342 2 K 2 - # N& 2 + 2 + 2  2 + 2 + 6/54  344(! $ $ 6 7 $ 6 7 # N& 6 2 K # P& 6 2 K  * # "ASE1 2 K  2 6SENSING N& # N& 6 # N& 6 # # —& 6 2 P&K6 2 6CC   + 2 - + 2 - $ ,, 5#  ,-$ 2 + 2 + N& - P&K6 # # N& 6 2 K 1 342  K   2 # N& ,, $ 2 +  N& 6 344(25 # N& 6 2 2  7 K  + 2 —& 6 # 6 $ 6SENSING 2 7 K 2 # —& 6 , % M( 344(2! $  # P&6 K  2 1 -*$4   2  "5,      2  6CC # $ ,-$  5" + 2 67 —& 6 344(! $ 344(! $ N&6 # N&6 + 2  P&6 # —&6 # 2 K "ASE1 342  2  PIN P& K6 2 +   5 ,$ :#$ '$ # P& 6 6CC 2 K K 2 + # N& 6  , 2 K  6 $ N& 6AC  2 K  5!   # N&6 2 +    1 34'$."3$  $ $ 2 N& ,,  2 $ # ,,  # N& 6 2 4 1   6 $  %   N& 6 #  + 2 34'$."3$ 6 $ 6 2 + 2 +  2 34'$."3$  1 #     # N& 6   6CC A ()$,!-0 B  # N&6 2 + 2 +  ,-$ 2 2 +   -5,4 +   '.$   #3   # N&   2      $ (6' "//4 '.$ #& 2& 63     344(! /54 5 ,6 ' 2 # K  N&6 + 2 6/54 N& 6 # ,$ K  2 2 K # N&6 6## # N& 6 1 3-$" # !-V —& 6 Doc ID 17003 Rev 1 2/4 Schematic diagram 1 STEVAL-ILH002V1 Schematic diagram STEVAL-ILH002V1 2 Revision history Revision history Table 1.
