ST ILB001V2 User Manual
36 W - 220 Vac low-cost HF ballast demonstration board
Features
■ 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.
