Step-Up Regulator with 4A Integrated Switch
ISL97656
The ISL97656 is a high frequency, high efficiency current
mode control non-synchronous step-up voltage regulator
operated at constant PMW switching frequency. It has an
internal 4.0A, 120m ? Low side MOSFET and can deliver high
output current and efficiency over 90%. The selectable 640kHz
and 1.22MHz switching frequency allows use of smaller
inductor and faster transient response. An external
compensation pin gives the user flexibility in setting frequency
compensation allowing the use of low ESR ceramic output
capacitors.
When in shut down mode, ISL97656 draws current <1μA and
can operate at as low as 2.2V input. These features along with
higher switching frequency allows use of tiny external
components and makes it an ideal device for portable
equipment and TFT-LCD displays.
The ISL97656 is available in a 10 Ld TDFN package with a
maximum height of 1.1mm. The device is specified for
operation over the full -40°C to +85°C temperature range.
