Description

The IS32LT3177 and IS32LT3178 are temperature-stable adjustable linear current devices. To configure‚ only one resistor is necessary. The operating current can range between 10mA and 200mA. The devices can function from 2.9V to 40V input voltage with a minimum voltage headroom of 1.0V (Typ.) at 150mA. The device has a low dropout voltage and can drive LED strings close to the supply voltage without the use of switch capacitors or inductors.

Features:

  • Up to 1kHz PWM input (IS32LT3178 only)
  •  0.6%/K current roll off at high temp over 145°C for thermal protection
  •  Output current limit – Thermal shutdown
  • Up to 0.77W (SOT23-6) power dissipation in a small package
