The ISL97519AIUZEVALZ and ISL97519IUZEVALZ evaluation boards are used to evaluate the ISL97519A and ISL97519 step-up voltage regulators that operate with high frequency and high efficiency. These kits are designed to deliver over 90% efficiency and provide a dip switch that allows users to select either 600kHz or 1.2MHz switching frequency.

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.
