Ordering Information
Description
Highly integrated PWM controller, FAN6861 is
optimized for applications with motor load; such as
printer and scanner, which inherently impose some kind
of overload condition on the power supply during
acceleration mode. The two-level OCP function allows
the SMPS to stably deliver peak power during the motor
acceleration mode without causing premature shutdown
and while protecting the SMPS from overload condition.
The green-mode and burst-mode functions with a low
operating current (2.2mA maximum in green mode)
maximize the light load efficiency so that the power
supply can meet most stringent standby power
regulations.
The frequency-hopping function helps reduce electro-
magnetic interference (EMI) of a power supply by
spreading the energy over a wider frequency range.
The constant power limit function; minimizes the
components stress in abnormal condition and helps
designer to optimize the power stage more easily.
Many protection functions such; as OCP, OLP, OVP
and OTP, are fully integrated into FAN6861, which
improves the SMPS reliability without increasing the
system cost.
