Overview

The PT4121E is a high efficiency step-down controller. It is designed to operate in continuous conduction mode and drive single or multiple series connected LED efficiently from a voltage source higher than the total LED chain voltage. It operates with a wide input voltage from 6V to 60V and provides an externally adjustable output current. The PT4121E includes a high-side output current sense circuit, which uses an external resistor to set the nominal average output current, and a dedicated DIM input accepts either a DC voltage or PWM dimming. The PT4121E is available in SOT23-6 or SOP-8 packages.
