NCP1605DR2G, IC: PMIC; -500?800mA; SO16; 9?20V; Topology: boost
NCP1605DR2G is power factor controller (enhanced, high voltage and efficient standby mode). It is a controller that exhibits near-unity power factor while operating in fixed frequency, discontinuous conduction mode (DCM) or in critical conduction mode (CRM). Housed in a SOIC-16 package, the circuit incorporates all the features necessary for building robust and compact PFC stages, with a minimum of external components. In addition, it integrates the skip cycle capability to lower the standby losses to a minimum.
• Near unity power factor, synchronization capability, valley turn on
• Fixed frequency, discontinuous conduction mode operation
• Critical conduction mode achievable in most stressful conditions
• Lossless high voltage current source for start-up, soft skip cycle for low power standby mode
• Switching frequency up to 250KHz, VCC range from 10V to 20V
• High drive capability of -500mA / +800mA
• Signal to indicate that the PFC is ready for operation ("pfcOK" pin)
• O/P under and overvoltage protection, brown-out detection, soft-start for smooth start-up operation
• Overcurrent limitation, zero current detection protecting the PFC stage from inrush currents
• SOIC-16 package
