ISL97519AIUZ - Renesas Electronics

Description: The ISL97519A is a high frequency, high efficiency step-up voltage regulator operated at constant frequency PWM mode. With an internal 2. 0A, 200mΩ 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. When shut down, i
