General Description

The IS31PW3500 is a constant current step-up converter.

The step-up converter topology allows series connection of the white LEDs so the LED currents are identical for uniform brightness as well as constant output voltage to drive other devices.

The IS31PW3500 switches at 1.1MHz, allowing the use of tiny external components.
