DESCRIPTION
An external compensation pin gives the user greater flexibility in setting loop compensation allowing the use of low ESR Ceramic output capacitors. Soft-start is controlled with an external capacitor, which determines the input current ramp rate during start-up. When shut down, it draws＜10µA of current and can operate down to 2.5V input supply. These features along with 1.25MHz switching frequency makes it an ideal device for portable equipment and TFT-LCD displays. The EUP2627 is available in an 10-pin TDFN and MSOP-8 (EP) packages. The device is specified for operation over the full -40°C to +85°C temperature range. FEATURES
