... PWM switching SEL frequency to 620kHz. When connect F switching frequency is set to 1.25MHz. Shut-Down Control When the Shut-down pin is pulled down, the EL7516 is shut- down, reducing the supply current to <3µA. 10 EL7516 EL7516 does not use a level translator or ground-referenced threshold for the SHDN input. For different supply voltages, please refer to Figure 32 to choose the right input threshold voltages for SHDN, where VTP is about 1V ...
