EL7516IYZ集成電路（IC）的穩(wěn)壓器-DC-DC開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

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.
