CURRENT MODE PWM CONTROLLER

ABSOLUTE MAXIMUM RATINGS (Note 1)

Supply voltage, VCC

35V

Output current, IO

± 1A

Analog inputs, VI

-0.3V to 6.3V

Error amp output sink current, ISINK(EA)

10mA

Power dissipation (TA = 25 OC), PD

1W

Maximum juncture temperature, TJ

150 OC

Storage temperature range

-65OC to 150OC

Lead temperature (soldiering, 10 seconds)

THERMAL DATA

M PACKAGE:

Thermal Resistance-Junction to Ambient, θJA

D PACKAGE:

Thermal Resistance-Junction to Ambient, θJA

DM PACKAGE:

Thermal Resistance-Junction to Ambient, θJA

Junction Temperature Calculation: TJ = TA + (PD × θJA).

The θJA numbers are guidelines for the thermal performance of the device/pc-board system.

All of the above assume no ambient airflow.

95 OC/W

120 OC/W

165 OC/W
