ISL97516 is a high frequency, high efficiency step-up voltage regulator operated at constant frequency PWM mode from ISL.
The ISL97516 is a high‑frequency, high‑efficiency boost regulator that operates in constant‑frequency PWM mode. It features an internal 2 A, 200 mΩ MOSFET, selectable 600 kHz or 1.2 MHz switching frequency, and a shutdown current of less than 1 pA, making it suitable for portable equipment and TFT‑LCD displays.
Typical applications include TFT‑LCD displays, DSL modems, PCMCIA cards, digital cameras, and handheld devices. The device is offered in an 8‑lead MSOP package (max height 1.1 mm) and is specified for operation from –40 °C to +85 °C.
