DESCRIPTION

The MP44014 is a boundary conduction mode

PFC controller that provides simple, high-

performance, active power factor correction

using minimal external components.

The output voltage is regulated accurately by a

high-performance voltage mode amplifier with

an accurate internal voltage reference.

The precise, adjustable output over-voltage

protection greatly enhances system reliability.

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

can potentially eliminate the external R/C filter.

The extremely low start-up current, quiescent

current, and disable function reduces power

consumption, resulting in excellent efficiency

performance.

The MP44014 is available in a SOIC-8 package.

FEATURES

 Boundary Conduction Mode PFC Controller

for Pre-Regulator

 Zero-Crossing Compensation to Minimum

THD of the AC Input Current

 Precise Adjustable Output Over-Voltage

Protection

 Ultra-Low (15μA) Start-U p Current

 Low Quiescent Current (0.46uA) at OVP

Condition

 On-Chip Filter on Current Sense Pin

 Disable Function on ZCS Pin

 -750mA/+800mA Peak Gate Drive Current

 Available in SOIC-8 Packages

APPLICATIONS

 Offline Adaptors

 Electronic Ballast

 LLC Front End

 Other PFC Pre-Regulators

Operating junction temp. (T

Thermal Resistance

(5)

SOIC-8 ....................................90 ...... 45... C/W

NOTES:

1) Exceeding these ratings may damage the device.

2) Except ZCS pin, which is self limited.

3) The maximum allowable power dissipation is a function of the

maximum junction temperature T

(MAX), the junction-to-

ambient thermal resistance θ

, and the ambient temperature

. The maximum allowable continuous power dissipation at

any ambient temperature is calculated by

D(MAX)=(T

(MAX)-T

)/θ

. Exceeding the maximum

allowable power dissipation will produce an excessive die

temperature, causing the regulator to go into thermal

shutdown. Internal thermal shutdown circuitry protects the

device from permanent damage.

4) The device is not guaranteed to function outside of its

operating conditions.

5) Measured on JESD51-7, 4-layer PCB.
