ST ILB001V2 User Manual

36 W - 220 Vac low-cost HF ballast demonstration board
Power supply: 220 Vac
Power output: 36 W
Boost topology
Discontinuous-conduction mode
RoHS compliant
Description
The STEVAL-ILB001V2 demonstration board is a complete reference system for a simple cost­effective PFC (power factor corrector) using bipolar transistors and is intended for low-to­medium power HF ballasts.
The proposed bipolar PFC solution targets the low-cost HF ballast market up to 80 W as it provides a simple cost-effective solution without sacrificing THD and PF levels. No additional ICs are required for the PWM signal as the device uses just a power bipolar transistor and a closed­loop feedback which performs the duty cycle modulation and output power regulation.
