ISL97519AIUZ Description

The ISL97519A is a high-frequency, high-efficiency step-up voltage regulator operated at constant frequency PWM mode. With an internal 2.0A, 200m MOSFET, 

it can deliver up to 1A output current at over 90% efficiency. Two selectable frequencies, 600kHz, and 1.2MHz, allow trade-offs 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.
