EUP2624
620kHz/1.25MHz Step-up DC/DC ConverterDescription
The EUP2624 is a high performance current mode, PWM step-up converter with pin able operating frequency. With an internal 2.1A, 170mΩ MOSFET, it can generate 12V at up to 500mA output current from a 5V supply. The able 620kHz and 1.25MHz allows smaller inductors and faster transient response. 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 EUP2624 is available in an 8-pin MSOP package. The device is specified for operation over the full -40°C to +85°C temperature range.
