Step-Up Regulator with 4A Integrated Switch

开关稳压器 4 5A LCD DC:DC BOOSTG

The ISL97656IRTZ-TK 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 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.
