MP44014-A

Boundary Mode PFC Controller

The Future of Analog IC Technology

FEATURES

DESCRIPTION



Boundary Conduction Mode PFC Controller

for Pre-Regulator

Zero-Crossing Compensation to Minimum

THD of AC Input Current

Precise Adjustable Output Over-Voltage

Protection

The MP44014-A is a boundary conduction

mode PFC controller that provides simple and

high-performance active power-factor correction

using minimum external components.

The output voltage is regulated accurately by a

high-performance voltage-mode amplifier with

an accurate internal voltage reference.



Ultra-Low (15μA) Start-Up Current

Low Quiescent Current (0.46mA) at OVP

Condition

The precise adjustable output over-voltage

protection greatly enhances the system

reliability.



On-Chip Filter on Current Sense Pin

Enable/Disable and Open-Loop Protection

Function on FB

The on-chip R/C filter on the current sense pin

can potentially eliminate the external R/C filter.



-750/+800mA Peak Gate-Drive Current

APPLICATIONS

The extremely low start-up current, quiescent

current, and the disable function reduces the

power consumption, resulting in excellent

efficiency performance.



Offline Adaptors

Electronic Ballasts

LLC Front End

Other PFC Pre-Regulators

The MP44014-A is available in a SOIC-8.
