A8180 - 1.4A STEP-DOWN LED DRIVER

Datasheet Summary

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.

The device operates from an input supply between 6V and 36V and provides an externally output current up to 1.4A.

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.

AiT Semiconductor Inc. www.ait-ic.com A8180 36V, 1.4A STEP-DOWN LED DRIVER HIGH BRIGHTNESS WITH INTERNAL SWITCH 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. The device operates from an input supply between 6V and 36V and provides an externally output current up to 1.4A. Depending upon supply voltage and external components, this can provides up to 24 watts of output power. The A8180 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current. Output current can be adjusted by applying an external control signal to the 'ADJ' pin.
