NCP1631
Interleaved, 2-Phase Power
Factor Controller
The NCP1631 integrates a dual MOSFET driver for interleaved
PFC applications. Interleaving consists of paralleling two small
stages in lieu of a bigger one, more difficult to design. This approach
has several merits like the ease of implementation, the use of smaller
components or a better distribution of the heating.
Also, Interleaving extends the power range of Critical Conduction
Mode that is an efficient and cost−effective technique (no need for
low trr diodes). In addition, the NCP1631 drivers are 180° phase shift
for a significantly reduced current ripple.
Housed in a SOIC16 package, the circuit incorporates all the
features necessary for building robust and compact interleaved PFC
stages, with a minimum of external components.
General Features
Near−Unity Power Factor
Substantial 180° Phase Shift in All Conditions Including Transient
Phases
Frequency Clamped Critical Conduction Mode (FCCrM) i.e.,
Fixed Frequency, Discontinuous Conduction Mode Operation with
Critical Conduction Achievable in Most Stressful Conditions
FCCrM Operation Optimizes the PFC Stage Efficiency Over the
Load Range
Out−of−phase Control for Low EMI and a Reduced rms Current in
the Bulk Capacitor
Frequency Fold−back at Low Power to Further Improve the Light
Load Efficiency
Accurate Zero Current Detection by Auxiliary Winding for Valley
Turn On
Fast Line / Load Transient Compensation
High Drive Capability: −500 mA / +800 mA
Signal to Indicate that the PFC is Ready for Operation (“pfcOK”
Pin)
VCC Range: from 10 V to 20 V
