PT4205 Datasheet (PowTech) - 1.2A Step-down HB LED Driver

PT4205, 1.2A Step-down HB LED Driver

The PT4205 is a continuous conduction mode inductive step-down converter, designed for driving single or multiple serie connected LEDs efficiently from a voltage source higher than the total LED chain voltage.

The device operates from an input supply between 5V and 30V and provides an externally adj
