MP44014-A – BOUNDARY MODE PFC CONTROLLER

ABSOLUTE MAXIMUM RATINGS ⁽¹⁾

Supply Voltage VCC .............. -0.5V to Self Limit

Zero Current Sensing (ZCS) . -0.3V to Self Limit

Other Analog Inputs and Outputs -0.3V to 6.5V

ZCS Max. Current.....................-2.0mA to 10mA

Continuous Power Dissipation (T_A= +25°C) ⁽²⁾

SOIC8........................................................ 1.4W

Junction Temperature………………… …..150C

Lead Temperature (Solder).......................260C

Storage Temperature............... -55C to +150C

Thermal Resistance ⁽⁴⁾

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

θ_JA

θ_JC

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

calculated

the maximum

D(MAX)=(T_J(MAX)-T_A)/θ_JA.

Exceeding

allowable power dissipation produces an excessive die

temperature, causing the regulator to go into thermal

shutdown. Internal thermal shutdown circuitry protects the

device from permanent damage.

Recommended Operating Conditions ⁽³⁾

Supply Voltage VCC ......................13.8V to 21V

Operating Junction Temp. (T_J). -40°C to +125°C

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

operating conditions.

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