Notes: 1. Rated voltages are with reference to the AGND and PGND terminal.

2. For the direction of Rated currents, (+) denotes the current flowing into the IC, and (–) denotes the current

flowing out of the IC.

3. Ambience temperature, Ta is 25 degrees centigrade.

4. Transient current when driving a capacitive load.

5. Rated currents of the terminals listed below:

COMP, CSO1, CSO2

6. Rated voltages of the terminals listed below:

in the case of R2A20114AFP: CS1, CS2, VAC, RS, FB, PD, BO, ERROR, E-DLAY, OFF, OVP2, FMC, FMR,

RT/SYNC, IRAMP, SYNC-O, CT, COMP, CSO1, CSO2

in the case of R2A20114ASP: CS1, CS2, VAC, RS, FB, BO, IRAMP, FM, RT/SYNC, CT, COMP, CSO1,

CSO2

7. Thermal resistor

in the case of R2A20114AFP:

ja = 85.3 degrees centigrade/W

in the case of R2A20114ASP:

ja = 120 degrees centigrade/W

These values are obtained under the condition that the IC is mounted on the glass epoxy board, of which size

is 50

 50  1.6 [mm] and wiring density is 10%.
