TB62D901FNG

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.

TB62D901FNG

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.
