DESCRIPTION
The MP44011 is a boundary-conduction–mode
PFC controller with an internal-harmonic–
injection function. It provides simple and high-
performance active power-factor correction with
minimal external components.
Compared against traditional boundary-
conduction–mode PFC controllers, the
harmonic-injection function makes the part
suitable for LED lighting applications.
In LED lighting applications with two-stage
structures, the harmonic-injection function can
effectively reduce bus capacitance between the
AC/DC and the DC/DC stage. In addition,
harmonic injection can reduce the transformer
size to save board space and BOM cost.
Also, the benefits of a harmonic-injection
function also apply to general boost or flyback
PFC applications.
The MP44011 is derived from the MP44010,
except with a harmonic-injection function.
The MP44011 is available in an 8-pin SOIC
package.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by D(MAX)=(T
J
(MAX)-
T
A
)/ θ
JA
. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
