600kHz/1.2MHz PWM Step-Up Regulator Evaluation Board
The ISL97519AIUZEVALZ and ISL97519IUZEVALZ evaluation boards are used to evaluate the ISL97519A and ISL97519 step-up voltage regulators that operate with high frequency...
Overview
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, 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. The ISL97519A is available in an 8 Ld MSOP package with a maximum height of 1. 1mm. The device is specified for operation over the full -40°C to +85°C temperature range.
