The EL7516 is a high frequency, high efficiency step-up
voltage regulator operated at constant frequency PWM
mode. With an internal 1.5A, 200mΩ MOSFET, it can deliver
up to 600mA output current at over 90% efficiency. The
selectable 600kHz and 1.2MHz allows smaller inductors and
faster transient response. An external compensation pin
gives the user greater flexibility in setting frequency
compensation allowing the use of low ESR Ceramic output
capacitors.
When shut down, it draws <10µA of current and can operate
down to 2.5V input supply. These features along with
1.2MHz switching frequency makes it an ideal device for
portable equipment and TFT-LCD displays.
The EL7516 is available in an 8 Ld MSOP package with a
maximum height of 1.1mm. The device is specified for
operation over the full -40°C to +85°C temperature range.
