STEVAL-ILB001V2
36 W - 220 Vac low-cost HF ballast using the bipolar solution for PFC

The STEVAL-ILB001V2 board is a complete reference system for a simple cost-effective PFC (power factor corrector) using bipolar transistors and is intended for low-to-medium 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 additionals ICs are required for the PWM signal since the device uses just a power bipolar transistor and a closed-loop feedback that performs the duty cycle modulation and output power regulation.
The active PFC solution with bipolar transistor adopts the boost topology operating in discontinuous-conduction mode.
