NCP1652, NCP1652A
High-Efficiency Single
Stage Power Factor
Correction and Step-Down
Controller
The NCP1652 is a highly integrated controller for implementing

power factor correction (PFC) and isolated step down ac ? dc power
conversion in a single stage, resulting in a lower cost and reduced part
count solution. This controller is ideal for notebook adapters, battery
chargers and other off ? line applications with power requirements

between 75 W and 150 W. The single stage is based on the flyback
converter and it is designed to operate in continuous conduction
(CCM) or discontinuous conduction (DCM) modes.
The NCP1652 increases the system efficiency by incorporating a
secondary driver with adjustable nonoverlap delay for controlling a

switch in the primary or both. In addition, the controller features a
proprietary Soft ? Skip ? to reduce acoustic noise at light loads. Other
features found in the NCP1652 include a high voltage startup circuit,
voltage feedforward, brown out detector, internal overload timer, latch
input and a high accuracy multiplier.
