Very low component count: 2 chips + 7 passive components Meets EN55015 standards WITHOUT EMI capacitor Extended life time of the fluorescent lamp due to smooth and single shot ignition High inherent reliability and extended life time of the starter
PENTAWATT HV EFS21-TL5
DESCRIPTION The EFS Kit is a 2 chips set used with 7 additional passive components, for Glow switch Starter. The ASDTM (Application Specific Discretes) includes a bi-directional Power Switch and a Power Supply for the driver. The driver provides a program to ensure a fully optimised linear fluorescent lamp ignition.
ASD is a trademark of STMicroelectronics.

When the starter has to be protected against over-temperature, over-current or short circuit, it is recommended to implement a thermal fuse in series with the starter. To meet (IEC 926) standards, a capacitor (f.i. 5nF) can be connected between pin 3 and pin 4 of the ASDTM. BOARD ASSEMBLY PCB with Pentawatt HV and SO14
DRILL and CUT the track for SHORT preheat --> for LONG preheat -->
Pin 2 is the preheat time select pin. To select a short preheat time, drill to cut the Vcc to pin 2 track at the metallic hole. To select a long preheat time, drill to cut the GND to pin 2 track. The layout must be configured for either choice to avoid supply short circuit.
