NCP1602BOOSTGEVB

NCP1602GEVB 160‐W, Wide Mains, PFC Stage Driven by the NCP1602 Evaluation Board User's Manual www.onsemi.com EVAL BOARD USER’S MANUAL Introduction and high-efficiency are the key requirements. Extremely slim, the NCP1602 evaluation board is designed to be less than 13 mm high. This low-profile PFC Stage is intended to deliver 160 W under a 390-V output voltage from a wide mains input. This is a PFC boost converter as used in flat TVs, high power LED street light power supplies, and all-in-one computer supplies. The evaluation board embeds the NCP1602 AEA-version which is powered by an external VCC. With the help of an external dc source, apply a VCC voltage that exceeds the NCP1602−AEA start-up level (18.2 V max) to ensure the circuit starts operating. The VCC operating range is from 9.5 V up to 30 V. Housed in a TSOP6 package, the NCP1602 is designed to drive PFC boost stages in so-called Valley Synchronized Frequency Fold-back (VSFF). In this mode, the circuit classically operates in Critical conduction Mode (CrM) when VCTRL pin voltage exceeds a product version programmable voltage level. When VCTRL pin voltage is below this programmable level, the NCP1602 linearly decays the frequency down to about 20 kHz, when the load current is nearly zero. VSFF maximizes the efficiency throughout the load range. Incorporating protection features for rugged operation, it is furthermore ideal in systems where cost-effectiveness, reliability, low stand-by power Table 1.
