NCP5010 500mW White LED Boost Converter
The NCP5010 is a fixed‑frequency PWM boost converter optimized for constant‑current white‑LED applications. It delivers up to 500 mW output power to 2‑5 series‑connected LEDs and uses a single resistor to set LED current, with optional PWM control via the CTRL pin.
The device includes True‑Cutoff, over‑voltage and short‑circuit protection, operates from 2.7 V to 5.5 V input, and is housed in a compact 1.7 × 1.7 mm 8‑pin flip‑chip package. Detailed electrical characteristics, pin functions, and package dimensions are provided for designers.

The device operates from 2.7 V to 5.5 V input.
It can provide up to 500 mW of output power to 2‑5 series‑connected white LEDs.
A single resistor sets the LED current, and the CTRL pin can be PWM‑modulated to adjust the current.
