MP171 –NON-ISOLATED OFFLINE REGULATOR
ABSOLUTE MAXIMUM RATINGS (1)
DRAIN to SOURCE (TJ = +25°C)-0.3 V to 700 V
All other pins................................-0.3 V to 6.5 V
Thermal Resistance (4)
TSOT23-5..............................100..... 55... °C/W
SOIC-8....................................96...... 45... °C/W
θJA
θJC
(2)
Continuous power dissipation.....(TA = +25°C)
NOTES:
TSOT23-5.................................................... 1 W
SOIC-8......................................................... 1 W
Junction temperature................................150°C
Lead temperature .....................................260°C
Storage temperature................ -60°C to +150°C
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ(MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowance continuous power dissipation at
any ambient temperature is calculated by PD(MAX)=(TJ(MAX)-
TA)/θJA. Exceeding the maximum allowance power dissipation
will produce an excessive die temperature, causing the
regulator to go into thermal shutdown. Internal thermal
shutdown circuit protects the device from permanent damage.
3) The device is not guaranteed to function outside of its
operating conditions.
Recommended Operating Conditions (3)
Operating junction temp (TJ).... -40°C to +125°C
Operating VCC range ...................5.5 V to 5.7 V
4) Measured on JESD51-7, 4-layer PCB.
