AC/DC Step-Down Conversion Type LED Lighting Driver
1. General
The TB62D901FNG is a constant current driver IC ideal for
use in the step-down AC/DC conversion type LED lighting
applications.
The TB62D901FNG features architecture with automatic Off
time adjustment control that can be used to achieve minimum
LED current variations by the effect of fluctuated input voltage
or change of LED forward voltage.
The device allows linear dimming or PWM dimming. It has
extensive detection functions that are thermal shutdown,
over-current detection, over-voltage detection, under-voltage
lockout, and current sensing input terminal (ISEN1) open
detection.
