Product Overview NCP1607: Power Factor Controller, Cost Effective For complete documentation, see the data sheet Product Description The NCP1607 is an active power factor controller specifically designed for use as a pre-converter in ac/dc adapters, electronic ballasts, and other medium power off line converters (typically up to 300W). It utilizes Critical Conduction Mode (CRM) to ensure unity power factor across a wide range of input voltages and power levels. The NCP1607 minimizes the number of external components. The integration of comprehensive safety protection features makes it an excellent choice for designing robust PFC stages. Features Benefits • Pin to Pin Compatible with Industry Standards • Programmable Overvoltage Protection • Built-in Under Voltage Protection • High Precision Voltage Reference (1.6% over the Supply Voltage and Temperature Range) • Very Low Startup Current Consumption ( 40 uA) • Low Typical Operating Current (2.1 mA) • +500 mA / -800 mA Totem Pole Gate Driver Applications • Second source • Design flexibility and rugged design <cr> NCP1607B: further reduces losses • Open loop protection • Better output voltage accuracy End Products • Any Power Factor Correction stage typically under 300 W • • • • • Electronic Ballast LCD TV Plasma TV Desktop PC AC Adapters Part Electrical Specifications Product Compliance Status PFC Mode Freque Control Topolo ncy Mode gy Operati on fSW Typ VCC (kHz) Max (V) Drive Cap.
