EUP2627
620kHz/1.25MHz Step-up DC/DC Converter
DESCRIPTION
The EUP2627 is a high performance current mode, PWM
step-up converter with pin selectable operating frequency.
With an internal 3.5A, 160mΩ MOSFET, it can generate
12V at up to 500mA output current from a 5V supply. The
selectable 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 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.
