ISL97519AIUZ, DC-DC импульсный повышающий стабилизатор, регулируемый, 2.3В-5.5В (Vin), 2.3В-25В, 2А, MSOP-8

The ISL97519AIUZ is a high-frequency high efficiency step-up Voltage Regulator operated at constant frequency PWM mode. With an internal 2A, 200mR MOSFET, it can deliver up to 1A output current at over 90% efficiency. Two selectable frequencies, 600kHz and 1.2MHz, allow tradeoffs between smaller components and faster transient response. An external compensation pin gives the user greater flexibility in setting frequency compensation allowing the use of low ESR ceramic output capacitors. When shut down, it draws <,1µA of current and can operate down to 2.3V input supply. These features, along with 1.2MHz switching frequency, make it an ideal device for portable equipment and TFT-LCD displays.

• Adjustable soft-start
• Internal thermal protection
• >,90% Efficiency
