EVAL_16W_66V_BCK_CE

Overview

16W single end cap T8 lighting demo board using CoolMOS™ CE in SOT-223 package

The SOT-223 packaged CoolMOS™ CE superjunction MOSFET (IPN60R3K4CE) (600V, 3.4Ω) is used as the main switch for this Single End Cap T8 LED lamp drive board, high line input, 16W/66V output converter. The converter is using ICL8201 (SOT23-6-1), average current controlled, non-isolated single stage buck topology in a cascade structure LED driver. The distinguishing features of this reference design are high efficiency and power factor with single stage design, critical conduction operation mode with single choke (without auxiliary winding), truly regulated output current over a wide output voltage range, good EMI performance and various modes of protections for high reliability with small form factor which can easily fit into a single end cap of a standard T8 LED lamp.
