Overview

TS19370 Boost (Step-up) WLED Driver with OVP SOT-26 Pin Definition: 1.
SW 6.
Input 2.
Ground 5.
OVP 3.
Feedback 4.
CTRL General Description The TS19370 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current.
The device can drive 2 ~ 9 LEDs in series from a Li-Ion cell.
Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.
The output capacitor can be as small as 0.
22µF, saving space versus alternative solutions.
A low 95mV feedback voltage minimizes power loss for better efficiency.
Additional feature include over output voltage limiting when LEDs are disconnected.
