*1: Electrical characteristics show the characteristic ratings guaranteed when operating the ICs under the measurement conditions described in the above table.
*2: Efficiency is calculated from the following formula.
η (%) =
VO·IO
× 100
VIN·IIN
*3: Pin 6 and pin 11 are the SS pins. Soft start at power on can be performed with capacitors connected to these pins. The outputs can also be turned ON/OFF with these pins. The
outputs are stopped by setting the voltages of these pins to VSSL or lower. SS-pin voltages can be changed with open-collector drive circuits of transistors.
When using both the soft-start and ON/OFF functions together, the discharge currents from C4 and C5 flow into the ON/OFF control transistors respectively. Therefore, limit the
currents securely to protect the transistors if C4 and C5 capacitances are large. The SS pins are pulled up to the power supply in the ICs, so applying the external voltages are
prohibited.
