ISL97656 Datasheet | Renesas

Step-Up Regulator with 4A Integrated Switch 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, 120mΩ Low side MOSFET and can deliver high output current and efficiency over 90%. The selectable 640k Hz and 1.22MHz switching frequency allows use of smaller inductor and faster transient response. An external pensation pin gives the user flexibility in setting frequency pensation 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 ponents 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...
