The NCP1612 is active power factor corrected (PFC) controller specifically designed for use as a boost pre-converter in ac-dc adapters, flat TVs, lighting ballasts and other medium powered offline applications. The controller is based on an innovative Current Controlled Frequency Foldback(CCFF) method. In this mode, the circuit classically operates in Critical conduction Mode (CrM) when the inductor current exceeds a programmable value. When the current is below this preset level, the NCP1612 linearly reduces the frequency down to about 20 kHz when the current is at a null. CCFF maximizes the efficiency at both nominal and light load. In particular, the standby losses are reduced to a minimum. The controller features a robust suite of protection features to properly handle an array of power supply operating and fault conditions. This device is particularly suited a PFC stage for LLC controllers due to its dedicated PFC_Okay Output.
NCP1612A1DR2G is a PWM controller manufactured by ON Semiconductor. It is a high-performance, low-cost, single-phase, current-mode, pulse-width modulation (PWM) controller. It is designed to provide a cost-effective solution for high-efficiency, low-cost, single-phase, AC-DC power conversion. The NCP1612A1DR2G features a wide input voltage range of up to 400V, a wide operating temperature range of -40°C to +125°C, and a high-frequency switching frequency of up to 500kHz. It also features a low-power standby mode, a low-ripple current mode, and a low-noise operation. The NCP1612A1DR2G is suitable for a wide range of applications, including AC-DC power supplies, DC-DC converters, and motor drives. It is also suitable for LED lighting, telecom, and industrial applications. (For reference only)
