Description
The A8180 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage.
Features
- Simple low parts count.
- Internal 36V NDMOS switch.
- Up to 1.4A output current.
- Single pin on/off and brightness control
using DC voltage or PWM.
- Soft Start.
- High efficiency (up to 97%).
- Wide input voltage range: 6V to 36V.
- Output shutdown.
- Up to 1MHz switching frequency.
- Inherent open-circuit LED protection.
- Typical 3% output current accuracy.
- High-side current sense.
- Hysteretic control: no compensation.
- Adjustable constant LE.
