NCL30060GEVB Off‐line Critical Conduction Mode PFC LED Driver Evaluation Board Users Manual Description Value Unit EVAL BOARD USER’S MANUAL Input Voltage Range 90 − 305 V rms Line Frequency Range 45 – 66 Hz The compact evaluation board is constructed with Output Current 700 mA through-hole components on the top and surface mount Output Voltage Range 10 – 41 V dc components on the bottom side. This driver was designed to Maximum Output Power 25 W meet safety agency requirements but has not been evaluated for compliance. When operating this board, observe safe Power Factor (Typical) 0.99 − standard working practices. High voltages are present and THDi (Typical) 10 % caution should be exercised when handling or probing Efficiency (Typical) 87.5 % various points to avoid personal injury or damage to the unit. Introduction Figures 1 and 2 illustrate the top and bottom sides of the The NCL30060 is intended to control a high performance evaluation board. AC input power connects to the block critical conduction mode (CrM) LED driver providing high labeled J1. Terminals are marked “L” and “N” representing powe
