Notes: 1. Rated voltages are with reference to the GND terminal.

2. For rated currents, inflow to the IC is indicated by (+), and outflow by (–).

3. Shows the transient current when driving a capacitive load.

4. This is the rated voltage for the following pins:

NC

5. This is the rated voltage for the following pins:

FB, OVP2, RT, TL, RAMP-GAIN, SS, RAMP

6. Minus value is peak voltage. Do not impress the DC voltage of the minus.

7.

ja = 120°C/W

This value is a thing mounting on 40

a glass epoxy board of wiring density 10%.
